Question

(b) A gas exerts pressure on the walls of the container​

Answer 1

Answer:

The pressure exerted by a gas is due to the random motion of particles in the gas. Gases have weak intermolecular forces and the particles in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exerts pressure on the gas.

Answer 2

Gases exert pressure on the walls of the container because the gas molecules. ... Therefore, the molecules are in random motion. Due to this motion, the molecules collide with the walls of the container and exert a force on the walls. Thus, a pressure is exerted on the walls.
