Question

a gas excert pressure on the wall of the container. give reason​

Answer 1

Because the particles of gaseous state move about randomly at high speed. Due to this random movement, the particles hit each other and also the wall of container. This is because a gas exert pressure on the wall of the container.

Answer 2

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
