What term describes how a blow dryer transfers thermal energy? convection radiation thermal expansion conduction

CONVECTION

Explanation:

In blow dryer the phenomenon of heat transfer is very simple.

First of all the heating coil in the wire will heat up by using electrical current

Then this heating coil develop the thermal energy and the blower in the coil will blow out all its thermal energy outwards

Here blower forcefully pushes the air molecules which are heated by the coil and this motion of air molecules will transfer the heat from one place to other

This phenomenon of heat transfer in which medium molecules carry thermal energy from one point to another point is known as convection flow of heat.
