NCERT Solutions for Class 11 Physics Chapter 13 - Kinetic Theory

In this chapter, we will study the kinetic theory. We will start with an introduction to the molecular nature of matter. We will also talk about different gases and the behavior of these gases. Then we move on to the kinetic theory of an ideal gas with the help of equations and examples. The law of equipartition of energy has also been explained in this chapter and connected to the previous sections. We will read about specific heat capacity again in this chapter in relation to the kinetic theory.

The chapter will then conclude by telling us briefly about the mean free path.

• The chapter begins by giving us a brief about scientists who have attempted to formulate their kinetic energy theories.
• We tread about how matter is made up of atoms and the atomic hypothesis.
• In gases, molecules are far away from each other as compared to solids and liquids.
• The chapter goes on to explain the molecular behaviour of gases and their breakdown.
• We learn about Boyle's law and Charles' law in relation to their study on gases.
• Numerous equations and diagrams also illustrate these laws.
• The chapter also contains a lot of questions of behaviours of gases and their answers.
• Kinetic theory of gases is based on a molecular picture of atoms.
• The chapter attempts to explain the kinetic theory of an ideal gas.
• We will learn about the pressure in an ideal gas and the kinetic interpretation of temperature.
• We also learn about the law of equipartition and its application to molecular particles.
• The chapter also tells us about the specific heat capacity in monatomic, diatomic, and polyatomic gases.
• We also read about the specific hearing capacity of solids and liquids.
• The chapter concludes by telling us about the mean free path.
• The average distance that a molecular can travel without colliding is called its mean free path.
