Radiation is the process by which heat is transferred by electromagnetic waves without requiring any medium. In this case, the heat from the fire is transferred to the hands through radiation. Conduction involves the transfer of heat through a medium or from one object to another in direct contact, but in this case, there is no direct contact between the hands and the fire. Convection involves the transfer of heat through the movement of heated fluids or gases, but again, there is no fluid or gas involved in this scenario. Vaporization involves the phase change from liquid to gas, and is not applicable in this case.
