Terms | Definitions |
|---|---|
 Temperature | Measure of the average kinetic energy of the individual particles |
| Farenheit | tempurature scale on which water freezes at 32 degrees and boils at 212 degrees |
| Celsius | Metric unit for measuring temperature; On this scale water freezes at zero and boils at 100. |
| Kelvin | SI unit for temperature; On this scale water freezes at 273 and boils at 373 |
| Absolute zero | The coldest temperature possible, 0 deg Kelvin, that can be reached. Particles have no kinetic energy. Degrees same as on Centigrade Scale. |
| Thermal energy | the total kinetic and potential energy of all the particles in a substance. |
| Freezing | the change in state from a liquid to a solid |
| Boiling | the application of heat to change something from a liquid to a gas |
| Heat | gain heat or get hot. |
| Conduction | Molecule to molecule transfer of heat |
| Convection | Transfer of heat by fluid movement or liquids |
| Convection current | a current caused by the rising of heated fluid and sinking of cooled fluid |
| Radiation | Transfer of energy that by electromagnetic waves |
| Conductor | a device designed to transmit electricity, heat, etc. |
| Insulator | A material that does not allow heat or electrons to move through it easily. Examples: styrofoam, paper |
| Specific heat | The amount of heat required to raise the temperature of 1kg of a substance 1 degree K |
