🧨 Postulates of kinetic theory of gases 🧨 ✨ A gas consists of large number of tiny particles called molecules. Volume occupied by gas molecules, is negligible as compared to the total volume of gas. ✨ There is continuous rapid random motion of gas molecules. The molecules collide with each other and against walls of container. ✨ The molecules are perfectly elastic bodies and there is no loss of kinetic energy during collisions. ✨ There are no attractive forces between the molecules of gas. ✨ The pressure exerted by a gas is due to bombardment of gas molecules against the walls of the container. ✨ The different molecules possess different velocities and hence different energies. The average K.E. is directly proportional to absolute temperature.
