The pressure exerted by a gas is a function of the frequency of collision between gaseous molecules. When gas molecules move, they collide with one another and with the walls of their container. These collisions create a force that is distributed over the area of the container, which is the pressure of the gas. The more often these collisions occur, the higher the pressure of the gas. Therefore, the pressure of a gas is directly proportional to the frequency of collision between its molecules. The total volume of the gas, the speed of the gaseous molecules, and the mass of each gaseous molecule can affect the frequency of collision between gaseous molecules, but they are not the primary factors that determine the pressure of the gas.
