Heat Transfer

Heat transfer is the transition of thermal energy from a heated item to a cooler item.

Type of heat transfer;

• Conduction


• Convection


• Radiation

Conduction is the transfer of heat between object that are in direct contact with each other.

Convection is the transfer of heat by movement of a heated fluid and occurs into a fluid or within a fluid, and cannot happen in solids.

Radiation is the transfer of heat energy through empty space. No medium is necessary; radiation works even in and through a perfect vacuum.
