Which one of the following is not an assumption in the kinetic theory of gases?

A

The volume occupied by the molecules of the gas in negligible

B

The force of attraction between the molecules is negligible

C

The collision between molecules are elastic

D

All molecules have same speed

Text Solution

Verified by Experts

The correct Answer is:
D
All molecules have same speed. This statement is true but this is not an assumption of kinetic theory of gases.
