Thermal Energy - 6.9AB

TermDefinition
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.
