Give a reason why gas exerts pressure on the walls of the container.
(N/A) In the gaseous state,the particles move randomly at high speeds. Due to this random movement,the particles collide with each other and also strike the walls of the container. This continuous bombardment of gas particles against the walls of the container exerts force per unit area,which is known as gas pressure.
