|---|---|
| temperature | a measure of how hot of cold something is; specifically, a measure of the average kinetic energy of the particles in an object. |
| thermal expansion | an increase in the size of a substance in response to an increase in the temperature of the substance. |
| absolute zero | the temperature at which molecular energy is at a minimum (0 kelvin, or -273.16 Celsius) |
| heat | the energy transfered between objects that are at different temperatures |
| thermal energy | the kinetic energy if a substance's atoms |

| thermal conductor | a material through which energy can be transferred as heat |
| thermal insulator | a material that reduces of prevents the transfer of heat. |
| convection | the transfer of thermal energy by the circulation of movement of a liquid of gas |
| radiation | the transfer of energy as electromagnetic waves. |
| specific heat | the quantity of heat required to raise a unit mass of a homogeneous material 1 K of 1 C in a specified way given constant pressure and volume. |
| states of matter | the physical forms of matter, which include solid, liquid, and gas |
| change of state | the change of a substance from one physical state to another |
| insulation | a substance that reduces the transfer of electricity, heat, of sound |
| heat engine | a machine that transforms heat into mechanical energy, or work |
