| state of matter | the physical form in which a substance can exist |
| solid | state of matter which has a definite shape and volume |
| liquid | state of matter which has a definite volume but can change shape |
| gas | state of matter which matter changes shape and volume |
| pressure | the 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 the gas increases as its pressure decreases |
| Charles's Law | for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature increases. |
| plasma | state of matter that does not have a definite shape or volume and whose particles have broken apart |
| change of state | the conversion of a substance from one physical form to another |
| melting | the change of state from a solid to a liquid |
| freezing | the change of state from a liquid to a solid |
| vaporization | the change of state from a liquid to a gas |
| boiling | the change of state from a liquid to a gas with heating |
| evaporation | change of state from a liquid to a gas without heating at the liquids surface |
| condensation | the change of state from a gas to a liquid |
| sublimation | the change of state from a solid to a gas |
