On the basis of kinetic theory of gases, explain how does a gas exert pressure?

Options

A. Suffer change in momentum when impinge on the walls of container
B. Are attracted by the walls of container
C. Continuously stick to the walls of container
D. Continuously lose their energy till it reaches wall

Answer

A

Explanation

From the assumption of KTG, the molecules of gas collide with the walls and suffer momentum change which results in force on the wall and hence pressure Hence option (a) is correct.
