About the chapter: HC Verma Class 11 Solutions Chapter 14
Molecules and atoms are what make up matters. A nucleus and electrons make up an atom. Nucleons are the positive-charged protons and neutrons that make up the nucleus. The nucleus is made up of different nucleons that are held together by nuclear forces. Electromagnetic forces work between two electrons and between an electron and the nucleus. The way an atom is put together is because of these forces.
The structure of a molecule is determined by the forces between its atoms, and the structure of a material is determined by the forces between its molecules.
Some physical properties of matter
1. Intermolecular Force
- An Intermolecular Force is the force that acts between two molecules that are close to each other. This force can be felt by every molecule in a solid.
- The ability of the body to go back to its original shape and size is called “elasticity.” It’s usually because molecules and atoms have forces that pull them together. The Elastic Force is the name for this force.
3. Perfectly Elastic Body
- Perfectly elastic bodies go back to their original shape and size as soon as the forces that changed them are gone.
- It is the opposite of being flexible. The body can’t get back to its original size and shape.
- Stress is the force per unit area on a body’s surface when it changes shape. It is the force that works against the force from outside the body.
- Stress = F/ A
- F = Area, A = Force
- Stress is measured in Nm-2.
Stress Types :
- Normal Stress
- Tangential Stress
Normal Stress: Stress that is perpendicular to the surface of the body is normal stress. It also comes in two kinds:
- Tensile Stress
- Compressive Stress
Stress that acts parallel to the surface of the body is called tangential stress.
6. Young’s Modulus
- The ratio of longitudinal stress to longitudinal strain is called Young’s modulus. It stays the same for all materials.
7. Bulk Modulus
- The bulk modulus of an object is the ratio of its longitudinal stress to its volumetric strain.
8. Shear Modulus
- The ratio of the tangential stress to the shear strain is the shear modulus.
9. Poisson’s Ratio
Lateral strain is the difference between the change in diameter (D) and the diameter of the body at the start (D). Longitudinal strain is the difference between a person’s new length (l) and their original length (l). Here, Poisson’s ratio is the ratio of the sideways strain to the lengthwise strain.

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.
