On the basis of kinetic theory of gases, the gas exerts pressure because its molecules :
(A) continuously lose their energy till it reaches wall.
(B) are attracted by the walls of container.
(C) suffer change in momentum when impinge on the walls of container.
(D) continuously stick to the walls of container.
Correct answer is (C)
On the basis of kinetic theory of gases, the gas exerts pressure because its molecules contain uniform speed, random motion and perform elastic collision with each other, as well as with the walls of container. As a result of which gaseous molecules suffer change in momentum when impinge on the walls of container
