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 into a gas. |
condensation | The change of state from gas to liquid. |
freezing point | temperature at which a liquid and changes into a solid. |
sublimation | the process in which a solid changes directly into gas. |
Phase- change diagram | drawing that shows the relationships among temperature and changes of state. |
plasma | a state of matter that forms when temperatures are enough to completely remove electrons from the atoms to which they were bound. |
