| Term | Definition |
|---|---|
| state of matter | the physical form of matter, which include solid, liquid, and gas. |
| solid | the state of matter in which the volume and shape of a substance are fixed. |
| gas | a form of matter that does not have definite volume or shape. |
| melting point | temperature at which a solid changes to a liquid. |
| vaporization | process in which a liquid changes to a gas. |
| boiling point | the temperature at which a liquid vaporizes and changes to a gas. |
| condensation | the change of state from a gas to a liquid. |
| freezing point | temperature at which a liquid changes into a solid |
| sublimation | the process in which a solid changes directly into a gas |
| Phase-change diagram | drawing that shows the relationships among temperature and changes of state. |
| plasma | a state of matter that forms when temperature are enough to completely remove electrons from the atome to which they were bound. |
