. A gas exerts pressure on the walls of the container. Give reason


Best Answer

Ans: The particles of a gas are constantly moving in all directions with different speeds. As a result of this random motion, the particles of a gas collide with one another and also against the walls of the container. As a result of these collisions, the gas exerts some force on the walls of the container. This force per unit area is called pressure of the gas. Thus, gases exert pressure due to the collisions of the particles of the gas on the walls of the containing vessel
