NCERT Solutions Class 10 Science Chapter 1 – Chemical Reactions and Equations

Students will learn about chemical reactions, how to write equations, how to do combination and decomposition reactions, and more in the first chapter of Class 10 NCERT Science. In the past, we’ve learned about how matter can change in both physical and chemical ways. When something changes chemically, we say that a chemical reaction has happened. A full chemical reaction is a symbolic representation of the reactants, the products, and their physical states. Students will also learn how to write a chemical reaction, which is a way to show a chemical reaction using symbols. It also talks about how different chemical equations can be balanced in different states.

Important Topics Covered in Class 10 Science Chapter 1 Chemical Reactions and Equations :

The second chapter of NCERT Class 10 Science is all about acids, bases, and salts. Students have learned in previous classes that acids and bases give foods their sour and bitter tastes, respectively. We all know that acids taste sour and turn blue litmus red, while bases taste bitter and turn red litmus blue. In this chapter, we’ll learn about how acids and bases react, how their effects cancel each other out, and many other interesting things we use every day.

[adinserter block=”6″]

Students will learn about the chemical properties of acids and bases, how acids and bases react with metals, how metal carbonates and metal hydrogen carbonates react with acids, how acids and bases react with each other, the reaction of metallic oxides with acids, and the reaction of a non-metallic oxide with a base, and many other chemical reactions.

NCERT Solutions Class 10 Science Chapter 3 – Metals and Non-metals

Students must have learned about different elements in previous classes. Based on their properties, elements can be grouped as metals or non-metals. In Chapter 3 of Class 10 Science, students will learn about how metals and non-metals behave physically. Metals are shiny, soft, and easy to shape. They also conduct heat and electricity well. Except for mercury, which is a liquid at room temperature, they are all solids. There are many ways to describe the physical properties of metals, such as their ductility, malleability, tensile nature, strength, etc. Metals and non-metals can be told apart by their physical properties.

Non-metals include carbon, sulphur, iodine, oxygen, hydrogen, and so on. Except for bromine, which is a liquid, the non-metals are either solids or gases. Under the subtopic chemical properties of metals, chemical reactions are discussed with oxygen gas, water, acids and other metal salts. Based on the reactivity series, the reactions and conditions will be different. On the list of how reactive things are, potassium is at the top and gold is at the bottom.

NCERT Solutions Class 10 Science Chapter 4 – Carbon and Its Compounds

In the last chapter, we talked about compounds that are important to us. In this chapter, we’ll learn about some more interesting compounds and how they work. Also, we will learn about carbon, an element that is very important to us both as a single atom and as a part of compounds. Carbon is a very useful element that makes up all living things and a lot of the things we use every day. Covalent bonds are made when two atoms share electrons so that their outermost shells can both be completely full.

Covalent bonds are made between carbon and other elements like hydrogen, oxygen, sulphur, nitrogen, and chlorine. Saturated and unsaturated carbon compounds are the two types of organic compounds. Compounds with only one bond are called “saturated.” Carbon compounds with a double or triple bond are called “unsaturated.” Methane, ethane, propane, butane, pentane, and hexane are all carbon and hydrogen compounds that are full of atoms.

The chapter also talks about some of the chemical properties of carbon and its compounds, like how they can burn, oxidise, add, or change. Ethanol and ethanoic acid are important carbon compounds that we use every day. The chemical structures and properties of soaps and detergents are looked at, and the difference between them is also talked about. Most of the time, detergents are used to make shampoos and clothes-cleaning products.

NCERT Solutions Class 10 Science Chapter 5 – Periodic Classification of Elements

In Standard 9, we learned that the matter around us is made up of elements, compounds, and mixtures and that each element has only one type of atom. When people first tried to put elements into groups, they put them into two categories: metals and non-metals. Dobereiner put the elements into groups of three, and Newlands came up with the Law of Octaves. Mendeleev put the elements in order based on how much their atoms weighed and how they behaved chemically.

He even guessed that some elements that hadn’t been found yet existed based on the gaps in his Periodic table. It became possible to make the modern periodic table. Mendeleev’s Periodic Law was changed, and the atomic number became the basis for the Modern Periodic Table. The Modern Periodic Law says that the properties of elements are a periodic function of their atomic number.

In this chapter, Periodic Classification of Elements, the elements in the Modern Periodic Table are put into 18 vertical columns called groups and 7 horizontal rows called periods. When put in this order, the properties of the elements, such as their atomic size, valency, or ability to combine, and whether they are metallic or not, show a pattern. The number of valence electrons in the outermost shell of an element’s atom tells us how strong it is. The radius of an atom is what is meant by the term “atomic size.”

In chemistry, the periodic table is one of the most important things to learn about. It is an important building block for all ideas that will come after. There are many ways to ask about the properties and how they change over time, and the Utopper NCERT Science Class 10 solutions have very clear and easy explanations, diagrams, and charts to help you understand. This chapter has different activities that are meant to help students learn better by making it more fun. The student is also shown three different types of the periodic table, which makes it easier to understand what the topic is about.

NCERT Solutions Class 10 Science Chapter 6 – Life Processes

Life Processes is Chapter 6 of NCERT Solution Class 10 Science. There are six things that all living things do to stay alive. They are movement, breathing, growing, reproducing, getting rid of waste, and eating. The chapter also talks about nutrition, which is the process of taking in food and using it for growth, metabolism, and repair. The stages of nutrition are eating, digesting, absorbing, transporting, assimilating, and getting rid of waste. Autotrophic nutrition and heterotrophic nutrition are two more types of nutrition.

[adinserter block=”6″]

Autotrophic nutrition involves taking in simple inorganic materials from the environment and using an outside energy source, like the Sun, to make complex high-energy organic material. Heterotrophic nutrition is when an organism eats complex food made by another organism. Parasitic nutrition, saprophytic nutrition, and holozoic nutrition are all types of heterotrophic nutrition.

The next topic is how people get their food. Ingestion, digestion, the esophagus, the stomach, the small intestine, bile, absorption, assimilation, and egestion are the different steps of nutrition. The next subtopic is breathing, which is a great place to learn about the human respiratory system. The human respiratory system is made up of the lungs, bronchi, larynx, pharynx, and other parts. During respiration, organic molecules like glucose are broken down to make ATP, which is a form of energy. ATP gives energy to other things going on in the cell.

Students learn about metabolism in Class 10 Science chapter 6. Metabolism is a chemical process that happens in the human body and is in charge of controlling the state of the cells in an organism. There are two types of metabolism: catabolism and anabolism.

This chapter will talk about breathing, which is how all living things take in oxygen and let out carbon dioxide. Some people say that breathing is the exchange of gases and the burning of food. Animals and mammals all have well-defined breathing systems that help them breathe.

Important Topics Covered in Class 10 Science Chapter 6 – Life Processes :

• Basic concept of nutrition, 
• Respiration,
• Transportation  
• Excretion in plants and animals.

NCERT Solutions Class 10 Science Chapter 7 – Control and Coordination

In Chapter 7 of Class 10, students learn about how the nervous system and hormones in their bodies help them control and work together. Reflex action, voluntary action, and involuntary action are the three types of responses that the nervous system can make. Electrical impulses are how the nervous system sends messages.

It gets information from our senses and acts through our muscles. Both plants and animals are able to work together chemically. Hormones that are made in one part of an organism move to another part of the organism to have the effect that is wanted. The way hormones work is controlled by a system of feedback.

One of the most interesting parts of Class 10 Science is the chapter on Control and Coordination. Through the different topics in this chapter, students can learn about so many different things. The students will learn about how animals’ nervous systems work and how plants work together. This chapter will explain a lot of ideas and answer a lot of questions about our bodies. This chapter also talks about the different hormones that plants use to do their jobs.

NCERT Solutions Class 10 Science Chapter 8 – How do Organisms Reproduce

In contrast to other life processes, reproduction is not necessary for an organism to stay alive. How do Organisms Reproduce chapter requires the cell to do the process to making a copy of the DNA and add more cellular parts. Different organisms have different ways of reproducing based on how their bodies are made. Many bacteria and protozoa just split into two or more daughter cells when they fission.

Organisms like hydra can grow back from pieces if they are broken. They can also make buds that turn into new people when they grow up. Some plants grow new plants from their roots, stems, and leaves. This is called vegetative propagation. These are examples of asexual reproduction, which is when a single individual can start a new generation. Sexual reproduction happens when two people come together to make a new person. Mechanisms for copying DNA make changes that are good for the survival of the species. Different ways of reproducing sexually make it possible for more variations to be made.

NCERT Solutions Class 10 Science Chapter 9 – Heredity And Evolution

We will learn about Heredity and Evolution in this chapter. We’ve seen that the process of reproduction leads to new people who are similar to the old ones but have some small differences. We have talked about how even asexual reproduction can lead to some differences. The rules for how traits are passed down in humans are based on the fact that both the father and the mother give the child almost the same amount of genetic material.

This means that DNA from both the father and the mother can affect each trait. In different species, what determines sex can be different. Changes in non-reproductive tissues that are caused by the environment are not passed on from one generation to the next. Speciation can happen when there are differences and places where they can’t meet. Organisms are put into groups that show how they are related to each other in terms of evolution. When we look at common ancestors, we can see that at some point in the past, life must have come from things that were not alive.

This chapter includes numerous basic principles and key notions that have a lot of weight and value when it comes to future study. Some of the principles presented in this chapter are heredity, evolution, inheritance rules, including Mendel’s contributions, and sex determination.

Important Topics Covered in Class 10 Science Chapter 9 – Heredity And Evolution :

• Mendel’s pea experiment.
• Sex determination.
• Acquired and inherited traits.
• Speciation.
• Homologous and analogous organs.
• Fossils.

NCERT Solutions Class 10 Science Chapter 10 – Light Reflection and Refraction

In NCERT Solution Class 10 Science Chapter 10, we will investigate the phenomena of light reflection and refraction using straight-line light propagation. These fundamental notions will aid us in our investigation of some natural optical phenomena. The chapter also examines spherical mirror reflection and refraction of light, as well as its applications in real life. Light is an energy source that produces the feeling of seeing in humans.

Light appears to move in straight lines. It is explained how to make convex and concave spherical mirrors. The numerous terminology associated with spherical mirrors, such as the center of curvature, radius of curvature, etc., focus, pole, and so on, are presented using ray diagrams. This chapter also discusses the applications of a spherical mirror. The mirror formula expresses the relationship between a spherical mirror’s object distance, image-distance, and focal length. A spherical mirror’s focal length is equal to half its radius of curvature.

Important Topics Covered in Class 10 Science Chapter 10 – Light Reflection and Refraction :

• Reflection of light
• Spherical mirrors
• Mirror formula and magnification
• Refraction of light

NCERT Solutions Class 10 Science Chapter 11 – The Human Eye and Colorful World

We learned about light and some of its qualities in the previous chapter. In this chapter, we will look at several natural optical phenomena. The chapter also discusses rainbow production, as well as the splitting of white light and the blue colour of the sky. One of the most valuable and sensitive sense organs is the human eye. It allows us to view the beautiful world and colours around us.

The ability of the eye to focus on both close and far objects by shifting its focal length is referred to as accommodation. The near point of the eye or the least distance of distinct vision is the shortest distance at which the eye can see objects clearly without strain. It is around 25cm for a young adult with normal vision.

Myopia, hypermetropia, and presbyopia are the most prevalent refractive vision abnormalities. Myopia, or short-sightedness, occurs when the picture of a distant object is focussed before the retina is adjusted by a concave lens of appropriate power. A convex lens of appropriate power is used to correct hypermetropia (far-sightedness-the image of adjacent objects is focused beyond the retina). In old age, the eye loses its ability to accommodate. Dispersion is the splitting of white light into its constituent colours. At sunrise and sunset, light scattering causes the sky to be blue and the Sun to be red.

This is another important chapter in the NCERT Class 10 Science syllabus. Students are expected to study this chapter carefully, keeping both biology and physics in mind. This chapter is very interesting because it gives a clear look at some of the things we see every day.

Important Topics Covered in Class 10 Science Chapter 11 – The Human Eye and Colorful World :

• Functioning of a lens in human eye
• defects of vision and their corrections
• applications of spherical mirrors and lenses.
• Refraction of light through a prism
• dispersion of light
• scattering of light
• applications in daily life (excluding colour of the sun at sunrise and sunset).

NCERT Solutions Class 10 Science Chapter 12 – Electricity

Electricity is a very important part of life in the modern world. It is a form of energy that can be controlled and is easy to use in homes, schools, hospitals, businesses, and other places. It is a thing that has to do with how charge moves.

An electric current is made up of a stream of electrons moving through a conductor. Usually, the direction of the flow of electrons is the same as the direction of the flow of the current. Ampere is the SI unit for measuring electric current. We use a cell or a battery to get electrons moving in an electric circuit. A cell generates a potential difference across its terminals. Volts are used to measure it (V).

Resistance is a property of a conductor that makes it hard for electrons to move through it. It decides how strong the current is. Ohm is the SI unit for resistance. Ohm’s law says that the difference in voltage between the ends of a resistor is directly related to the amount of current going through it, as long as the temperature stays the same.

A conductor’s resistance depends directly on its length, inversely on its cross-sectional areas, and also on its material. When you put several resistors in a line, their total resistance is the same as the sum of their individual resistances. W = V x I x t tells us how much energy is lost in a resistor. Watt is the unit of power (W). When 1 A of current flows at a potential difference of 1 V, 1 W of power is used. Kilowatt-hour is the commercial unit of electricity (kWh). 1kW h = 3,6000,000 J = 3.6 x 10⁶ J.

This is one of the most important chapters in the whole Science curriculum. It goes over some of the most important ideas about electricity, which are both very interesting and very useful, especially if the student is thinking about a career in Science.

Important Topics Covered in Class 10 Science Chapter 12 – Electricity :

• Electric current

NCERT Solutions Class 10 Science Chapter 13 – Magnetic Effects of Electric Current

Students will learn about magnetic fields and electromagnetic effects in this chapter. They will also learn about electromagnets, electric motors, and electric generators. Electromagnets and electric motors use the magnetic effect of electric current, and electric generators use the electric effect of moving magnets.

The needle of a compass is a small magnet. It has a north pole and a south pole. The north pole is the end that points north, and the south pole is the end that points south. In the area around a magnet where the force of the magnet can be measured, there is a magnetic field. A magnetic field is shown by its field lines. A field line is the path that an imaginary free north pole would tend to move along. A north pole placed at a certain point can be used to figure out the direction of the magnetic field at that point. Where there is more magnetic field, the field lines are closer together.

A magnetic field is created when an electric current flows through a metal wire. Around the wire, the field lines are made up of a series of concentric circles whose direction is determined by the right-hand rule. When an electric current flows through a conductor, a magnetic field forms around the conductor.

[adinserter block=”2″]

Electromagnetic induction is when a coil is placed in a place where the magnetic field changes over time. This causes a current to flow through the coil. If a magnet close to the coil moves while the coil stays still, the magnetic field may change. If the coil is near a current-carrying conductor, the magnetic field could change either because the current through the conductor changed or because the coil and conductor were moving.

Fleming’s right-hand rule shows the direction of the induced current. A generator turns the energy of moving parts into electricity. It works by causing an electromagnetic field to move something. A generator can be either an AC generator or a DC generator. The most important safety device is the fuse, which protects the circuits from overloading or short-circuiting.

As with the last chapter, there is a lot to learn and understand in this one. Electricity and magnetism are closely related, and many of the things we use every day are based on these ideas. It is important for the student to understand these ideas, not just for the test but also for his or her studies in grades 11 and 12.

In this chapter, students will learn how electric current affects magnetic fields. Diagrams of magnetic field lines are very important, and the NCERT solutions for Class 10 Science show them in a clear way. The chapter also talks about the magnetic field and force on a conductor that carries a current, which is an important subject for the exam.

Also covered are an introduction to the electric motor and how it works, electromagnetic interference (EMI), how an electric generator works, and how to draw household circuits. Students should also know the main differences between AC generators and DC generators.

Important Topics Covered in Class 10 Science Chapter 13 – Magnetic Effects of Electric Current :

• Magnetic field 
• Magnetic field lines
• Magnetic Field due to a current carrying conductor. 
• Magnetic field due to current carrying coil or solenoid.

NCERT Solutions Class 10 Science Chapter 14 – Sources of Energy

As our standard of living goes up, so do our energy needs. In order to get the energy we need, we try to use it more efficiently and find new sources of energy. The chapter talks about different kinds of energy sources, and most of them are ones that have been used for a long time. It includes hydropower plants, thermal power plants, and fossil fuels. There is also talk about the pros and cons.

After that, we talk about improvements to technology for using traditional sources of energy, like biomass and wind power. Next, students will learn about alternative or non-traditional sources of energy. It includes energy from the sun, which is made by the solar cell and solar panel. Tidal energy, wave energy, and ocean thermal energy are all ways to get energy from the sea.

Geothermal energy can also be made from the surface of the earth. Nuclear energy comes from the core of an atom, which is called the nucleus. The energy source we choose would depend on things like how easy and cheap it is to get energy from the source, how well the technology we have to use that source of energy works, and how it affects the environment. Many of the sources get their energy from the Sun in the end. All of the topics are broken down into their pros and cons.

Important Topics Covered in Class 10 Science Chapter 14 – Sources of Energy :

• Good Sources of Energy 
• Conventional Sources of Energy 
• Non – Conventional Sources of Energy 
• Fossils Fuels

NCERT Solutions Class 10 Science Chapter 15 – Our Environment

This chapter talks about how different parts of the environment affect each other and how our actions affect the environment. The different parts of an ecosystem depend on each other. The producers make sure that the rest of the ecosystem can use the energy from the sun. As we move from one trophic level to the next, we lose energy.

Because of this, there are only so many trophic levels in a food chain. The food chain is explained in detail with real-life examples from the forest, the grassland, and the pond. The environment is affected by what people do. Because of things like CFCs, the ozone layer is in danger. Since the ozone layer protects us from the Sun’s ultraviolet rays, this could hurt the environment. The trash we make can either break down on its own or can’t. Getting rid of the trash we make is causing big problems for the environment.

This chapter is becoming more and more important very quickly. The only thing that can save the world from ignorance and a growing population is knowledge. Because of this, this chapter is very important. Also, if you try to learn it in a systematic way, it is a very important chapter.

NCERT Solutions Class 10 Science Chapter 16 – Sustainable Management of Natural Resources

In the last class, we learned about natural resources like soil, air, and water, as well as how nature recycles different parts over and over again. In this chapter, we’ll look at some of the things we have and how we use them. Our resources, such as forests, wildlife, water, coal, and oil, need to be used in a way that will keep them around for a long time.

We can make less of an impact on the environment if we follow the “Refuse, Reduce, Reuse, Repurpose, and Recycle” rule. Forest resources have to be managed in a way that takes into account the needs of many different groups. Putting water to use by building dams has effects on society, the economy, and the environment.

There are alternatives to building big dams. These are specific to a place and can be made so that local people can have more control over their local resources. Coal and oil, which are fossil fuels, will eventually run out. Because of this and the fact that burning them hurts the environment, we need to be careful about how we use these resources.

Management of natural resources is another important topic that can earn you points if you do it right. This chapter is also about something that is important for preserving the earth’s resources. It is important because it makes people aware of and shines light on important, life-saving issues that need immediate attention.

When you read this chapter, you will learn about interesting things like how to use natural resources in a way that is good for the environment and why we need to change the way we manage our resources. It also talks about wildfires and forests, the resources they give us, water, and other resources that don’t grow back, like oil and coal.

Important Topics Covered in Class 10 Science Chapter 16 – Sustainable Management of Natural Resources :

• 5 R’s to save Environment 
• Forest and Wildlife 
• Water for All
• Coal and Petroleum 
• Natural Resource Management
