| heat | energy transfered between objects |
| specific heat | the amount of energy needed to raise the temperature of an object by 1 degree Celcius or 1 K |
| temperature | the measure of the amount of thermal energy in an object |
| bimetallic strips | a two part piece of metal used to control thermostats |
| states of matter | solid, liquid or gas |
| change of state | when an object melts, freezes or vaporizes |
| absolute zero | the temperature at which molecular activity is minimal |
| conduction | energy transfer through touch |
| convection | energy transfer through fluids |
| radiation | energy transfer through space |
| chemical change | a reaction where substances change into different substances by recombining atoms |
| thermal energy | the energy recognized as heat |
| thermal expansion | objects take up more space as they are heated |
| thermal conductor | an object that allows thermal energy to pass through it |
| thermal insulator | an object that does not allow thermal energy to pass through it easily |
| thermal pollution | when thermal energy causes a problem in the environment |
