HC Verma Solutions Vol 1 Chapter 14 Some Mechanical Properties of Matter is a very important chapter and consists of questions which are frequent in competitive examinations. While studying this chapter students will come across questions related to finding stress, strain and compression etc. They will have to solve questions related to comparing compression, strain, and stress of metals such as steel and copper. In order to help, students master the concepts discussed in chapter 14 of HC Verma book part 1 and develop better problems skills we are offering free solutions on this page. These will also help students boost their preparation for JEE exams. With these solutions, students will further get to learn solving problems such as:
- Finding the tension in the string when the load is suspended.
- Questions on Lateral displacement, pressure and surface energy, etc.
- Solve problems on the viscous force, hydrostatic force, the terminal velocity of raindrops and more.
The HC Verma solutions contain answers that are arranged in a systematic manner for easy navigation and learning.
Some of the important topics that students will also learn in this chapter are;
- Molecular Structure of a Material
- Hooke’s Law and the Modulii of Elasticity
- The relation between Longitudinal Stress and Strain
- Elastic Potential Energy of a Strained Body
- Determination of Young’s Modulus in Laboratory
- Surface Tension
- Surface Energy
- Excess Pressure Inside a Drop
- Excess Pressure/ in a Soap Bubble
- Contact Angle
- Rise of Liquid in a Capillary Tube
- Flow through a Narrow Tube: Poiseuille’s Equation
- Stokes’ Law
- Terminal Velocity
- Measuring the Coefficient of Viscosity by Stokes’ Method
- Critical Velocity and Reynolds Number
Important Questions In Chapter 14
1. What will happen to a spring’s elastic potential energy when it is dissolved in acid in a compressed state?
2. Let’s take a glass capillary tube and dip it at one end in water. We will notice the water rise in the tube. This also results in increased gravitational potential energy. What can you state about this action considering the conservation of energy? Does it violate it?
3. What happens when small drops of water are used to form a bigger drop?
(a) energy is absorbed (b) energy is liberated (c) energy is either liberated or absorbed as per the nature of the liquid (d) energy is neither liberated or absorbed
4. A falling solid sphere has a terminal velocity of 20 m/s in air. IWhat will happen if it falls in a vacuum?
(a) terminal velocity will be less than 20 m/s (b) terminal velocity will be more than 20 m/s (c) terminal velocity will be 20 m/s (d) Terminal velocity does not exist.
5. To which state does the property of viscosity belong to;
(a) Solids (b) Liquids (c) Both (d) Liquids and Gases
