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 momentum. According to Newton's second law of motion,the rate of change of momentum is equal to the force exerted. Since the molecules exert a force on the walls over a specific area,this results in the pressure exerted by the gas. Therefore,the pressure is due to the transfer of momentum from the molecules to the walls of the container.
