What is causes gas pressure? * The average kinetic energy of the molecules. The amount of space the gas takes up, The amount of gas in a container. The particle collisions between the gas particles and the container.

Gas pressure is primarily caused by the particle collisions between the gas particles and the walls of their container. When gas molecules move, they frequently collide with one another and the container’s surfaces, transferring momentum and creating force. This force, when distributed over the surface area of the container, results in the pressure we measure! Additionally, the average kinetic energy of the molecules plays a crucial role in determining the pressure; as the temperature increases, the average kinetic energy of the molecules increases as well. Faster-moving molecules collide with the walls of their container more often and with greater force, which in turn raises the pressure of the gas. So remember, more speed equals more pressure!
