which best explains how thermal energy is transferred when someone holds a hand above a fire? it is transferred by conduction and radiation. it is transferred by only convection. it is transferred by only conduction. it is transferred by radiation and convection.
Answer
Brief Explanations:
Conduction requires direct contact, which is not the case here as there is air between hand and fire. Radiation is the transfer of energy in the form of electromagnetic waves and occurs between the fire and the hand. Convection is the transfer of heat by the movement of a fluid (in this case, hot - air rising from the fire). So both radiation and convection are involved.
Answer:
It is transferred by radiation and convection.
