Definition of gas pressure: It is the force per unit area caused by gas molecules colliding with the walls of their container.

Definition of gas pressure: Gas pressure is the force that is created when gas molecules move around quickly and hit the walls of the container they are in. These molecules are constantly moving and bouncing around, and every time they hit the wall, they push against it a little bit. All of these tiny pushes add up to create pressure.

Molecular motion: Gas pressure arises from constant, random collisions of countless gas molecules with the container’s surface.

Molecular motion: Gas molecules never stop moving. They zoom around in all directions, and because they are so small and light, they bounce off everything — each other and the sides of their container. This random and constant movement causes them to collide with the container walls, and those collisions are what we feel as gas pressure.

Collision frequency and force: The more frequent and forceful the molecular collisions, the higher the resulting gas pressure.

Collision frequency and force: If the molecules move faster or there are more of them, they will hit the walls more often and with more force. The more collisions there are, and the harder they hit, the higher the pressure becomes. So if you heat the gas or add more gas into the same space, the pressure will go up.
