| Convection | The movement of fluids due to the differences in density that are caused by temperature variations. |
| Conduction | The transfer of energy as heat through a material |
| Radiation | Energy transferred as electromagnetic waves, such as visible light and infrared waves. |
| Temperature | A measure of how hot or cold something is; specifically a measure of the average kinetic energy of the particles in an object |
| Heat | The energy transferred between objects that are at different temperatures. |
| Conductor | A material through which energy is easily conducted. |
| Insulator | A material that is a poor conductor of energy. |
| Absolute zero | The temperature at which all molecular motion stops. |
