Question

Why do gases exert pressure on walls of container?

Answer 1

Explanation:

particles present in the gaseous state have high inter molecular space and less inter molecular force of attraction.

Due to this the particals of matter move around hit each other and the walls of the container, thereby exerting force. This force per unit area is the pressure exerted by the particals of matter.

Answer 2

Explanation:

Gases have high KE due to which particles keeps on moving rapidly as a result particles hits the walls of the container and exert pressure.
