How gas particles produce pressure

How gas particles produce pressure

Gas particles move rapidly and randomly, travelling in straight lines between collisions. When a particle collides with a wall and rebounds, its velocity changes, so the wall exerts a force on the particle and the particle exerts an equal and opposite force on the wall.
