| characteristic that distinguishes one type of matter fom another and can be observed without changing the identity of the substance. | physical property |
| state in which matter can exist: sold, liquid, jas, or plasma | phase |
| phase in which matter has a definite shape and volume | solid |
| solid in which the particles are arranged in a regular pattern. | crystal |
| matter with no definite shape but with a definite volume | liquid |
| phase in which matter has no definite shape or volume | gas |
| phase in which matter is extremely high in energy and cannot be contained by ordinary matter. | plasma |
| change of a solid to a liquid | melting |
| temperature at which a substance changes from the solid phase to the liquid phase. | melting point |
| change of a liquid to a solid | freezing |
| temperature at which a substance changes from the liquid phase to the solid phase | freezing point |
| change of a liquid to a gas | vaporization |
| vaporization that takes place at the surface of a liquid | evaporation |
