which type of heat transfer causes a spoon to become warm when it is placed in a cup of hot…

Brief Explanations:

Conduction is the transfer of heat through direct contact. When a spoon is placed in hot - water, heat is transferred from the hot water to the spoon through direct molecular contact. Absorption is not a main type of heat transfer in this context. Radiation is heat transfer through electromagnetic waves and doesn't require a medium or direct contact. Convection involves the movement of fluids (liquids or gases) to transfer heat, which is not the case here as the heat transfer is mainly through direct contact between the spoon and water.

Answer:

D. conduction
