About the chapter: HC Verma Solutions Class 12 Physics Chapter 41
When gas is ionised and an electric current flows across it, this is called an electric discharge. Depending on many factors, the discharge may give off visible light. In order to make lighting sources and high-voltage electrical equipment, scientists look into the way gases discharge electricity.
At atmospheric pressure, gases aren’t really good at turning electricity on and off. So, you need something called a “gas-discharge tube” to send an electric current through a gas. Most of the time, a gas discharge tube is a glass tube with two electrodes sealed into its walls. When a voltage is put between the two electrodes, the pressure of the gas inside the tube goes down. Eventually, the pressure drops to the point where a current flows too fast and the gas starts to glow. Most of the time, the gleam shows up when the pressure is between 5 torr and 15 torr.
Neon signs work like this: a tube with an electrode at each end is filled with a low-pressure gas, and the electrodes are given a high voltage (usually between 1000 and 5000 volts). The colour of the glow depends on what kind of gas is inside the tube. Neon gives off a red glow, helium gives off a pale, dull glow, and argon gives off a blue glow. Mercury vapour also gives off blue light, and sodium vapour gives off a colourless light.
Neon signs are made with either neon gas or a mix of neon gas and mercury vapour. Using multicoloured tubing or fluorescent coatings on the inside of the tubes can make a range of colours that can be seen.
Terms relating to Chapter 41
Electrons: An electron might be a stable elementary particle with a negative electrical charge. Unlike protons and neutrons, electrons don’t have even smaller parts that make them up. Each electron has a charge of 1.602 x 10-19 coulomb and a mass that is much smaller than that of a neutron or proton. An electron has a mass of 9.10938 x 10-31 kg. Most of the time, this is about 1/1836 the weight of a proton.
e– is often used as a symbol for an electron. The particle that is the opposite of an electron and has a positive charge is called a positron or an antielectron. The symbol for a positron is either e+ or +. When an electron and a positron hit each other, they destroy each other and release energy in the form of gamma rays.
Protons: The charged particles inside the nucleus of an atom are called protons. The electromagnetic force pushes the protons apart, but the strong interaction, which is stronger over short distances, pulls them back together (these distances are a few FM or 10-15 m). The size of a proton is only about 10-15 m, which is 10,000 times smaller than the size of an atom. Even though protons are so small, they push against each other with about 100 N of force, which is like the weight of a small dog.
The charge on a proton is exactly the same as the charge on an electron but in the opposite direction. So, the number of electrons in an atom that is neutral is usually the same as the number of protons. Quarks, which are smaller particles, are the building blocks of both protons and neutrons. The number is the number of protons in an atom’s nucleus. This number tells us what kind of element an atom is. In other words, the element changes when the number of protons changes.
The atomic number, which is the number of protons, changes when a nucleus decays in any of its many ways. (3) The problem with changing the number of protons on purpose in a nucleus is what made alchemy fail for so long. Alchemy was an attempt in the Middle Ages to turn lead into gold.
Neutron – The neutron has significant advantages over other types of radiation when studying the microscopic structure and dynamics of condensed matter (solids and liquids) in our surrounding environment. Neutron scattering tells us a lot about how condensed matter behaves at the microscopic level. It has a big impact on our experimental and theoretical understanding of materials, from magnetism and superconductivity to chemical surfaces and interfaces.
A neutron is an elementary particle that is not charged and has 1,839 times the mass of an electron. Neutrons are stable when they are in an atomic nucleus, but they only live for about 1000 seconds when they are free. Since the neutron and the proton make up almost all of the mass of an atomic nucleus, they are both called nucleons.

FAQ ( Frequently Asked Questions )
1. Where can I get HC Verma solutions?
Ans – Utopper offers HC Verma answers that are correct and have been worked out by experts. Our website, utopper.com, is where you can find HC Verma solutions. This is free, and if you study these answers, you can pass the JEE.
2. How Should I Study HC Verma For IIT JEE Preparation?
Ans – Students have used this book to study for JEE for the past twenty years, and they have all passed JEE. So, this book can’t be ignored. Once you’ve figured out how to solve the example problems, you can compare your answers to those in the book. If your answer is right, compare it to the solution to make sure you used the right steps to get there. If your answer is wrong, look at the other solutions to figure out “why” your answer is wrong. If you made a math or procedure mistake, you’ll need to find a way to fix it if you want to do well on an exam like the JEE.
3. Is HC Verma enough for the JEE Advanced?
Ans – Is the H.C. Verma book enough to prepare for the JEE Main and Advanced? H.C. Verma is a good book for getting ready for the JEE, and it goes into detail about each topic.
4. Who is better: SL Arora or HC Verma?
Ans – If you want to take the boards, SL Arora will do fine, and you won’t have to take HCV. But if you are studying for competitive exams like IIT/JEE mains or advanced, you should definitely go for HCV because it has more advanced problems and will help you solve more complicated problems.
5. What is the best way to solve HC Verma?
Ans- Start from the beginning. Don’t skip around or move in a random way. Before you try to solve the problems, read the whole chapter. Take your time reading and make sure you understand the ideas.
6. Is only HC Verma Solutions enough for NEET Preparation?
Ans – HC Verma won’t help you enough on its own. It will help you with one subject, but you’ll need to look at other books for the rest. You can also use NCERT books, which are very helpful for passing the NEET exam. For the NEET exam, you need a lot of practice, which you can get from reading about many different things.
