Behavior of Gases
The molecules of a gas in a closed container, such as a balloon, are not only constantly moving. They are also constantly bumping into each other and into the sides of their container. The sketch in Figure shows how this happens. The force of the particles against whatever they bump into creates pressure.
The particles of a gas keep bumping into the sides of its container.
