Answers
Answer:
Why does gases exert pressure?
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.
Explanation
The pressure exerted by a gas can be explained by the simple kinetic theory of gases. Gases possess high kinetic energy and negligible force of attraction so they can move constantly moving with high speed in all directions. Due to this intense random motion of particles, the particles hit each other and also hit the walls of the container with a force. These collisions of the gas particles with the walls of the container exert pressure on the walls of the container.
