A person leaning against a cold cement block wall would lose heat by the process of:
A) convection.
B) evaporation.
C) radiation.
D) conduction.

Question

Quizplus · Accepted Answer

The process of losing heat by direct contact with a cooler object is known as conduction. In this scenario, the person is in direct contact with the cold cement block wall, and therefore the heat loss will occur through conduction. Convection involves the transfer of heat through fluids, evaporation occurs when a liquid changes to a gas and requires a source of energy, and radiation involves the transfer of heat through electromagnetic waves, none of which apply to this scenario.
