| Thermal Energy | Energy that the particles of a substance have. |
| Melting | The change in state from a solid to a liquid. |
| Freezing | The change in state from a liquid to a solid. |
| Vaporization | The change in state from liquid to vapor. |
| Evaporation | Vaporization which occurs only on the surface of a liquid |
| Boiling | The type of vaporization that takes place inside a liquid as well as at the surface. |
| Condensation | A change in state when gas particles lose enough thermal energy to become a liquid. |
| Sublimation | A change in state occuring when the surface particles of a solid gain enough energy to become a gas. |
| boiling point | The specific temperature when a liquid boils. |
