Question

Quizplus · Accepted Answer

When a person is standing outside on a cool, calm night, the primary way in which the body will lose heat is through radiation, which is the transfer of heat through electromagnetic waves. Convection, which is the transfer of heat through movement of fluids, is less likely to occur in a still night. Conduction, which is the transfer of heat through direct contact, also plays a lesser role in heat loss in such situations. Evaporation, which involves the removal of heat through liquid turning into vapor, is not a factor here as the woman is not sweating or in contact with any wet materials.
