In defining heat, which of the following describes the direction of energy transfer?

Question

Quizplus · Accepted Answer

Heat is defined as the flow of energy from an object at a higher temperature to an object at a lower temperature. Therefore, the correct direction of energy transfer is from hot objects to cold objects. Choices A and C relate to the direction of fluid flow, while choice B incorrectly suggests that heat flows from cold objects to hot objects, which violates the second law of thermodynamics.
