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.
