Which term describes the energy that flows from a higher temperature to a lower temperature?

• A. Heat
• B. Temperature
• C. Work
• D. Energy

Answer: (A)

Heat is the energy in transit that moves from a higher temperature object to a lower temperature object. It isn’t a property of an object itself, but the way energy flows when there is a temperature difference. Temperature describes how hot something is, while heat describes the transfer of energy due to that difference. Work is a different mode of energy transfer that involves a force acting through a distance. Energy is a broad term for the ability to do work or transfer heat, but heat specifically refers to transfer driven by temperature differences. For example, a hot mug warms the surrounding air because heat flows from the mug to the cooler air until they reach the same temperature.
