Why does a gas exert pressure on the walls of a vessel in which it is kept?

Solution

The concept of pressure can be explained with the help of the kinetic molecular theory of gases.
The force of attraction between the gas particles is negligible.
They possess greater kinetic energy and are in random motion.
Due to this motion, they collide with each other and also with the walls of the container.
The collision of gas particles with the walls is the cause of the pressure created.
