There are three mechanisms of heat transfer, namely conduction, convection, and radiation. We probably encounter each one of these in our daily lives. Each one of these mechanisms is even exhibited in our small desktop 3D printers.What's the fastest method of heat transfer?
Answer: Radiation is the fastest mode of transfer of heat, because radiation travels at the speed of light, which is very quick. The slowest mode of transfer of heat is conduction because it takes place from particle to particle. Radiation is considered the fastest mode of heat transfer as it travells as fast as light.
