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).
