Heat
»Energy transfer between objects that are different temperatures.

Conduction
»The movement of heat or electricity through something (such as metal or water).
Example: Metal spoon in soup

Convection
»The transfer of thermal energy by the circulation or movement of a liquid or gas.
Example: water boiling on the stove

Radiation
»The transfer of energy as electromagnetic waves.
Example: Solar radiation from Sun

Example: Metal spoon in soup
*Heat always travels from a warmer area to a colder area.
