Heat

Heat is the energy that moves between objects of different temperatures.

There are three forms of heat energy transfer: Conduction, convection and radiation.

Conduction is the transfer of heat between two objects (solids) that are touching.

Convection is the transfer of heat within a liquid or a gas.

Radiation is the transfer of heat without matter to carry it.
