Substances that Exist as Gases

Interactive: What is Pressure?

Gases have no definite shape or volume. When they are constrained to a container, we can measure the pressure they exert on the container walls. The model shows the inside (yellow atoms) and outside (green atoms) of a balloon. The teal barrier represents the wall of the balloon. Add atoms to the balloon and watch what happens. Because of the increased pressure, the volume increases!
