On collision with the walls there is a change in momentum

Vedclass · Answer

(C) According to the kinetic theory of gases,gas molecules are in constant random motion. When these molecules collide with the walls of the container,they undergo a change in velocity,which results in a change in momentum. According to Newton's second law of motion,the rate of change of momentum is equal to the force exerted. Since force is exerted on the walls over a specific area,this results in the pressure exerted by the gas. Therefore,the correct answer is $C$.

The pressure exerted by the gas on the walls of the container is because:
