| gas | state in which matter has changes in both shape and volume |
| pressure | amount of force exerted on a given area |
| Boyle's Law | states that for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases |
| Charles's Law | states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature decreases |
| plasma | the state of matter that does not have a definite shape or volume and whose particles have been broken apart |
| change of state | change from one physical form to another |
| melting | change of state from a solid to a liquid |
| freezing | change of state from a liquid to a solid |
| vaporization | the change of state from a liquid to a gas |
| boiling | vaporization that occurs throughout a liquid |
| evaporation | vaporization that occurs at the surface of a liquid below its boiling point |
| condensation | change of state from a gas to a liquid |
| sublimation | change of state from a solid directly to a gas |
