Thermal Energy - 6.9AB
Term | Definition |
---|---|
Thermal Energy | The total kinetic (motion) energy of tiny particles that make up matter. The faster the particles move, the warmer the matter becomes. |
Conduction | Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch. |
Convection | Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, more dense fluids. |
Radiation | The transfer of energy by the movement of electromagnetic waves or subatomic particles. |
Heat | Energy transferred between two objects of different temperatures; energy will continue to move in a predictable pattern from warmer site to cooler site until all sites have reached the same temperature. |
Convection Current | A circular movement of fluids caused by the rising of hotter, less dense fluid and the falling of cooler, more dense fluid. |
Law of Conservation of Energy | Energy can neither be created nor destroyed; energy just changes form. |
Temperature | Average kinetic energy of all the particles in a material; measured by a thermometer in degrees (usually Celsius or Fahrenheit). |
Energy | The ability to do work |
Substances | matter; a material of a particular kind or constitution |
Thermal Energy Transfer | The movement of heat from one place to another. |
