State the assumptions of the kinetic theory of gases.

Explanation

Assumptions of kinetic theory of gases :
1. Nature of gas molecules :
(a) A gas consists of very large number of tiny particles called molecules .
(b) The molecules are rigid and perfectly elastic spheres of very small diameters i.e., `10^(-10)m`.
2. Random motion of gas molecules :
(a) The molecules are always in a state of random motion. This state is also called as molecular chaos.
(b) Between any two successive collisions, the molecule follows a straight line path with constant velocity known as free path.
