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

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 mechanism 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.

Answer:

D. conduction
