Heat Transfer
The three types of heat transfer differ according to the nature of the medium that transmits heat: Conduction requires contact. Convection requires fluid flow. Radiation does not require any medium. Conduction is heat transfer directly between neighboring atoms or molecules. Usually, it is heat transfer through a solid.
