Unit 8: The Behavior of Gases

Believe it or not, gases are such a different state of matter than solids and liquids that we are going to study them separately. A gas is a state (or phase) of matter where all intermolecular attractions between particles have been overcome and the particles are separate from each other with empty space between. Because the particles of a gas are separated and constantly moving gases have certain properties: they have no shape, they expand to fill up an entire container, and they can be compressed to take up a smaller volume.
