3 Types Of Heat Transfer

Atoms and molecules are capable of transferring heat. Atoms are in motion at all times. The motion of molecules and atoms is the source of heat or thermal energy, and every matter contains this energy. The more molecules move, the more heat energy there will be. 

3 Types of Heat Transfer

Conduction Direct contact between objects results in the transfer of heat. This is the most common form of heat transfer. The burners on stoves conduct heat energy to the bottom of a pan placed on top of them when cooking. The pan then conducts heat to its contents. The hot oil in a deep fryer also uses conduction heating to cook the food when it comes in contact with it. Furthermore, conduction heat is responsible for moving heat from the outside to the inside of the food.

Convection Heat is transferred through fluid motion (like air or water). In contrast to conduction, convection involves the movement of thermal energy by moving hot fluid (as opposed to making other materials hot by wiggling atoms). Differences in density are usually responsible for this movement. 

Radiation Radiation is the transmission of heat from one place to another without leaving the intervening medium. It occurs in objects that emit electromagnetic radiation. No medium is required for the heat to travel.
