The Kinetic Theory of Gases Chapter 19 The Kinetic Theory of Gases In this chapter we will introduce the kinetic theory of gases, which relates the motion of the constituent atoms to the volume, pressure, and temperature of the gas. The following topics will be covered: Ideal gas law Internal energy of an ideal gas Distribution of speeds among the atoms in a gas Specific heat under constant volume Specific heat under constant volume Adiabatic expansion of an ideal gas (19–1)
