Write down the postulates of kinetic theory of gases.

Explanation

(i) All the molecules of a gas are identical, elastic spheres .
(ii) The molecules of different gases are different .
(iii) The number of molecules in a gas is very large and the average separation between them is large than size of the gas molecules.
(iv) The molecules of a gas are in state of continuous random motion .
(v) The molecules collide with one another and also wiith the walls fot eh container
(vi) These collisions are perfectly elastic so that there is no loss of kinetic energy during collisions
(vii) Between two successive collisions, a molecule moves with uniform velocity.
(viii) THe molecules do not exert any force of attraction or repulsion on each other except during collision . The molecules do not posses any potential energy and the energy is wholly kinetic.
(ix) The collisions are instanteneous . the time spent by a molecule in each collision is very small compared to the time elpsed between two consecutive collisions.
(x) These molecules obey Newton's laws of motion even through they move randomly.
