| Fahrenheit scale | Water freezes at 32 degrees and boils at 212 degrees on this scale. |
| Celsius scale | Water freezes at 0 degrees and boils at 100 degrees on this scale. |
| Kelvin scale | Water freezes at 273 degrees and boils at 373 on this scale. |
| absolute zero | At this temperature, no more energy can be removed from matter. |
| heat | The movement of thermal energy from a substance of higher temperature to a substance of lower termperature. |
| conduction | Heat is transferred from one particle of matter to another without the movement of matter itself. |
| convection | The transfer of heat by the movement of currents. |
| convection current | When heated water rises and cooler water takes its place a circular motion results. |
| radiation | Transfer of heat by electromagnetic waves. Matter is not needed for this transfer of thermal energy. |
| insulator | A material that does not conduct heat well. |
| specific heat | The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin. |
