On the basis of kinetic theory of gases, the gas exerts pressure because its molecules:
- continuously lose their energy till it reaches wall.
- are attracted by the walls of container.
- continuously stick to the walls of container.
- suffer change in momentum when impinging on the walls of container.
Correct answer: suffer change in momentum when impinging on the walls of container.
Solution
The correct option is right because, according to the kinetic theory of gases, gas molecules collide with the walls of the container, and these collisions result in a change in momentum, which is what generates pressure.
