Chapter 14 - Heat - Misconceptual Questions: 3

Answer

Choice A.

Work Step by Step

Thermal equilibrium means that heat does not transfer between objects, i.e., the objects are at the same temperature. The internal energy depends on the amount of substance and the temperature of the substance. The hot object is not necessarily the object with the higher internal energy. For example, a hot brick will have less internal energy than all the water in a swimming pool. Heat refers to the transfer of energy between objects that are not at the same temperature; it is not a property of an object and an object cannot “have” heat.
