| A measure of the average kinetic energy of te particles in the object | Temperature |
| The sum of the kinetic energy and potential energy of all the particles in an object | Thermal energy |
| Thermal energy that flows from something at a higher temp. To something at a lower temp. | Heat |
| The amount of heat that is needed to raise the temp. Of 1kg of some some material by 1°c | Specific heat |
| The transfer of the al energy by collisions between particles in matter | Conduction |
| The transfer of the al energy in a fluid by the movement of warmer and cooloer fluid from place to place | Convection |
