Gases exert a pressure on any surface with which they are in contact.
The amount of pressure exerted by the molecules of a gas depends on the force and frequency of the molecules towards the walls of its container. According to Boyle's Law, the volume of a fixed quantity of a gas at a constant temperature is inversely proportional to the pressure. Thus with temperature constant, as volume increases, the pressure decreases, and vice-versa. The Third Gas Law states that when the volume of a fixed mass of gas is maintained constant, pressure is directly proportional to absolute temperature. As the absolute temperature increases, the average kinetic energy of the molecules increases.
