Heat is a form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.

Heat transfer is the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
EX1.Hot air corn popper
EX2.Radiator
This heating method requires the movement of matter

Conduction is the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.
EX1 food heats plate
EX2 hugs
This method requires matter but not movement

the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and absorbed by another body by energy being (emitted as particles or waves)
EX1 heat from radiator
EX2 heat from washing machine
No matter required
