Answer: conduction heat transfer
Step-by-step explanation:
Heat transfer is the transfer of heat from one point to another as a result of temperature gradient between the two points. Heat can be transferred by three means; conduction (solids) , convection (fluids), radiation (electromagnetic radiation).
In the case above, the type of heat transfer is conduction because the heat travels through a solid material (iron) to the hand which are in contact with each other.
