Thermal Energy
| Term | Definition |
|---|---|
| temperature | A measure of the average energy of motion of the particles of a substance. |
| thermal energy | Heat energy, a form of kinetic energy associated with molecules in motion |
| solid | Definite shape and volume, molecules are tightly packed in a regular pattern, very little movement |
| liquid | definite volume but no definite shape, molecules are loosely packed and and flow against each other |
| gas | No definite shape or volume, molecules are very far apart and move freely |
| heat | thermal energy transfer |
| System | A group of parts that work together as a whole |
| kinetic energy | the energy an object has due to its motion |
| molecule | A group of atoms bonded together |
| atom | Basic unit of matter |
| boiling point | The temperature at which a liquid changes to a gas |
| melting point | The temperature at which a solid becomes a liquid |
| freezing | The change of state from a liquid to a solid |
| sublimation | A change directly from the solid to the gaseous state without becoming liquid |
| Celcius | Metric temperature scale on which water freezes at 0 degrees and boils at 100 degrees |
| Fahrenheit | The temperature scale on which water freezes at 32 degrees and boils at 212 degrees |
| Kelvin | SI unit for temperature |
| convection | The transfer of heat by the movement of a fluid |
| conduction | The direct transfer of heat from one substance to another substance that it is touching. |
| Radiation | The transfer of energy by electromagnetic waves |
