Hot cider is poured into a metal cup. Shortly thereafter the handle of the cup becomes hot. This is due to the process of

C) conduction.
D) will remain the same if the work done exceeds the heat added.

Question

Quizplus · Accepted Answer

The transfer of heat from the hot cider to the metal cup handle occurs through conduction, which is the transfer of heat through direct contact between two objects. As the hot cider comes in contact with the metal cup, the molecules in the metal vibrate, causing the handle to heat up as well. Radiation and convection may also be occurring, but the primary process in this scenario is conduction. The answer D is irrelevant and incorrect as it does not pertain to the given scenario.
