| Temperature | Measure of random motion of atoms of a substance |
| Celsius | Metric temperature scale used by most the world's citizens |
| Heat | Flow of thermal energy due to a temperature difference |
| List the phases of matter in order of increasing Thermal Energy | Solid, Liquid, Gas, Plasma |
| List phases in order of increasing density | Plasma, Gas, Liquid, Solid |
| Solid | Definite volume, Definite shape |
| Liquid | Definite volume, Indefinite shape |
| Gas | Indefinite volume, Indefinite shape |
| Plasma | most common phase found in universe |
| Condensation | Gas to Liquid |
| Evaporation | Liquid to Gas |
| Deposition | Gas to Solid |
| Sublimation | Solid to Gas |
| Freezing | Liquid to Solid |
| Melting | Solid to Liquid |
| Melting Point | physical property that shows temperature at which substance goes from solid to liquid |
| Boiling Point | Physical Property that shows the temperature at which a substance will go from a liquid to a gas |
| Putting ice in a drink | Heat flows from drink to ice |
| Holding a hot cup of coffee | Heat flows from coffee to hand |
| Radiation | Type of heat transfer that can occur in a vacuum |
| Convection | Heat transfer that occurs in liquids and gases through currents |
| Conduction | Type of heat transfer that occcurs by contact |
| Which heat transfer occurs best in solids? | Conduction |
| Thermal Equilibrium | When heat will no longer flow between two objects because they are at same temperature |
| Intermolecular Forces | Attraction between molecules of a substance; must be overcome before a phase change |
| Specific Heat | Amount of energy needed to change 1 kg of a substance by one degree Celsius |
