| Term | Definition |
|---|---|
| solid | a state of matter that has a definite shape and a definite volume |
| liquid | a state of matter that has no definite shape but has a definite volume |
| gas | a state of matter that has no definite shape or volume |
| crystalline solid | a solid that is made up of crystals in which particles are arranged in a regular, repeating pattern |
| fluid | a substance that can flow |
| amorphous solid | a solid made up of particles that are not arranged in a regular pattern |
| surface tention | the result of an inward pull among the molecules of liquid that brings the molecules on the surface closer together; causes the surface to at like a thin skin |
| melting | the change in state from solid to liquid |
| vaporization | the change in state from a liquid to gas |
| boiling point | the temperature at which a substance changes from a liquid to gas; the same temperature as the condensation point |
| melting point | the temperature at which a substance changes from a solid to a liquid; the same temperature as the freezing point |
| evaporation | the process that occurs when vaporization takes place only on the surface of a liquid |
| condensation | the change of state from gas to a liquid |
| freezing | the change in state from a liquid to a solid |
| boiling | the process that occurs when vaporization takes place inside a liquid as well as on top |
| sublimation | the change in state from a solid to a gas without passing through a liquid state |
| pressure | the force on a surface divided by the area of that surface |
| Boyle's Law | a principle that describes the relationship between the pressure and the volume of a gas at a constant temperature |
| Charles' Law | a principle that describes the relationship between the temperature and volume of gas at a constant pressure |
