Unit IX, Behaviour of Perfect Gases and Kinetic Theory of Gases holds 20 marks weightage along with Unit VII and Unit VIII. NCERT Grade 11 Chapter 13, Kinetic Theory is a part of Unit IX. In this chapter, behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules is explained. Kinetic Theory is being studied since the 19th century by scientists such as Newton, Boyle, Maxwell, Boltzman, Avogadro and others. This chapter gives an introduction to kinetic theory.
Molecular nature of matter, Behaviour of Gases, Kinetic Theory of an Ideal Gas, Pressure of an Ideal Gas, Kinetic Interpretation of Temperature, Law of Equipartition of Energy, Specific Heat Capacity, Monatomic Gases, Diatomic Gases, Polyatomic Gases, Specific Heat Capacity of Solids, Specific Heat Capacity of Water, Mean Free Path are the concepts dealt with in this chapter. Evolution of the study of Kinetic Theory over the time is explained theoretically in this chapter. Similarly, mathematical expressions, graphical and diagrammatic representations, numerical problems, derivations and examples where the students can relate the concepts with daily life instances make the chapter interesting.
Derivations based on laws have numerical problems that are solved for better learning and unsolved problems for practice are given to test the understanding of the students. Contribution by physicists from across the globe increases the significance of the chapter.NCERT Grade 11 Physics Chapter 13, Kinetic Theory is an important chapter as it builds the foundation for learning of further complex concepts of Grade 12 and thereafter.
