| temperature | The amount of heat energy in a substance, determined by the average kinetic energy if the molecules in the substance |
| heat energy | A form of energy produced by vibration of molocules that can be absorbed, given up, or transfered between substances |
| internal energy | The total amount of energy a substance contains |
| Kelvin | the SI temperature scale using units equivalent to Celcuis degrees and begining at absolute zero |
| absolute zero | The Temperature at which molocules do not move;the lowest temperature matter can have |
| conduction | The transfer of heat energy or electrons between objects in direct contact |
| convection | The transfer of heat energy by the movement of fluid |
| radiation | The transfer of energy by infrared rays |
| specific heat | The amount of energy necessary to raise temperature 1 g of a substance 1* C |
| boiling point | The temperature at which a substance changes from liquid to gas |
| calorie | The amount of heat nedded to raise the temperature of 1g of water 1* C |
| melting point | The temperature at which a substances changes from a solid to a liquid |
| thermal expansion | An increase in the volume of a substance due to an increase in heat energy |
