| Avogadro’s Law | gases at the same temperature |
| (Normal) Boiling Point | the temperature at which a phase change between liquid and gas occurs at 1 atm or 101.3 kPa; the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure. |
| Compound | pure substance composed of two or more different elements chemically combined. |
| Deposition | phase change from gas to solid. |
| Element | pure substance composed of one species of atoms. |
| Evaporation | phase change from liquid to gas. |
| Sublimation | phase change from solid to gas. |
| Temperature | a measure of average kinetic energy. |
| Charles Law | at constant pressure and mass |
| Boyles Law | at constant temperature and mass |
| ideal gas | a model of a gas in which the particles have no volume;do not attract or repel each other |
| Combined gas law | at constant mass |
