THERMAL ENERGY
6.9AB THERMAL ENERGY
Term | Definition |
---|---|
THERMAL ENERGY | Total kinetic (motion) energy of tiny particles that make up matter; the faster particles move, the warmer matter becomes. |
CONDUCTION | Transfer of thermal energy that occurs in solids, liquids, & gases when 2 substances of different temperatures touch. |
CONVECTION | Heat transfer caused by the rising of hotter, less dense fluids & the falling of cooler, more dense fluids. |
RADIATION | Transfer of energy by the movement of electromagnetic waves or subatomic particles. |
HEAT | Energy transferred between 2 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 | Circular movement of fluids caused by the rising of hotter, less dense fluid & 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 particles in a material; measured by a thermometer in degrees (usually Celsius or Fahrenheit). |
