| Temperature | A measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object. |
| Thermal Expansion | An increase in the size od a substance in response to an increase in the temperature of the substance. |
| Absolute Zero | The temperature at which molecular energy is at minimum (0 K on the Kelvin scale or -273.16 degrees C on the Celsius scale). |
| Heat | The energy transferred between objects that are at different temperatures. |
| Thermal Energy | The kinetic energy of a substance's atoms. |
| Thermal Conduction | The transfer of energy as heat through a material. |
| Thermal Conductor | A material through which energy can be transferred as heat. |
| Thermal Insulator | A material that reduces or prevents the transfer of heat |
| Convection | The transfer of thermal energy by the circulation or movement of a liquid or gas. |
| Radiation | The transfer of energy as electromagnetic waves. |
| Specific Heat | The quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 degree 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. |
