Fastest Mode : 1 Mark Radiation is the fastest mode of heat transfer, whereas conduction is the slowest mode of heat transfer. Radiation is fastest because it does not require any medium for heat transfer.

Heat transfer through conduction is slowest because firstly, it requires medium for heat transfer and secondly, the particles transfer heat on through vibrations and not by actual movement.
