Question

The gas exert pressure on the wall of container in which it is filled explain the statement

Answer 1

The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.

Answer 2

Particles of gases collide against the walls of the containing vessel and impact momentum to them, this is responsible for the pressure of gas.
