A gas exerts pressure on the walls of the container. Give reason.
→ The particles of gases do have a very large intermolecular space between them.
→ The particles of a gas are constantly moving in all the directions of the container at different speeds hence colliding with the walls of the container as well as with each other.
→ When particles collide they collide with a certain force.
→ This force per unit area is the called pressure of the gas.
→ Hence, gas exerts pressure on the walls of the container.
