Give the statement and postulates of kinematic molecular theory of ideal gases.

Que.: Give the statement and postulates of kinematic molecular theory of ideal gases.

Ans.:

• Maxwell and Boltzmann in 1859 developed a mathematical theory to explain the behaviour of gases. It is based on the concept that gas is made of a large number of molecules in a perpetual motion. This theory is therefore called as kinetic theory of gases.
The theory is based on the following assumptions:

1. A gas consists of extremely small discrete particles dispersed throughout the container.

2. Gas molecules are in constant random motion with high velocities.

3.Gas molecules can move freely, independent of each other.

4. There is no loss of kinetic energy of a molecule during a collision.

5. The pressure of a gas is due to the striking of gas molecules on the walls of the container.

6. The average kinetic energy molecules is the same at a given temperature.
