- In conduction, the heat flow is within and through the body itself. In contrast, in heat transfer by thermal radiation, the transfer is often between bodies, which may be separated spatially. Heat can also be transferred by a combination of conduction and radiation.

What is heat conduction example?
Conduction is when heat moves from one object to another object through direct touch. For instance, one piece of metal could conduct heat from another piece of metal if the two are touching.
Heat transfer is defined as the process in which the molecules are moved from the region of higher temperature to lower temperature. Conduction, convection, and radiation are the types of heat transfer.

Radiation involves the transfer of energy through electromagnetic waves, specifically infrared radiation in the context of heat transfer. Unlike conduction and convection, radiation does not require a medium; it can occur in a vacuum without the presence of any particles.
Conduction is the flow of heat energy through a material without overall movement of the material itself.
