Ans. (1)
Explanation:
According to kinetic theory of gases, molecules suffer change in momentum when impinge on the walls of container. Due to this they exert a force resulting in exerting pressure on the walls of the container.
Q. On the basis of kinetic theory of gases, the gas exerts pressure because its molecules:
(1) suffer change in momentum when impinge on the walls of container.
(2) continuously stick to the walls of container.
(3) continuously lose their energy till it reaches wall.
(4) are attracted by the walls of container.
