Thermal Energy

Thermal Energy Thermal energy is the total kinetic (motion) energy of the 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 Transfer of thermal energy from one place to another by the movement of fluids; occurs on a large scale in atmospheric gases, oceans, and Earth's mantle.
Radiation The transfer of energy by electromagnetic rays; may occur in empty space; matter need not be in direct contact or be present for the transfer of energy to occur.
Heat Heat is the 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 cyclical motion occurs because the density of a fluid is related to its temperature. Heated lower parts of the fluid are less dense than the cool parts. The less dense fluid rises and the denser fluid sinks due to gravity. This forms a circular pattern.
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).
