The term that describes heat moving from one location to another due to a temperature difference is known as what?

• A. Energy transfer
• B. Thermodynamics
• C. Heat transfer
• D. Phase change

Answer: (C)

Heat transfer describes the movement of thermal energy from a location at a higher temperature to one at a lower temperature because of that difference. It occurs through conduction (direct contact), convection (moving fluids or air), and radiation (energy traveling as heat waves). In HVAC work, this is what drives what we feel as heat moving from warm spaces to cooler ones or heat from a furnace reaching the rooms. Energy transfer is a broader idea that includes other ways energy can move, not just heat moving due to a temperature difference. Thermodynamics is the study of energy and its transformations, and phase change refers to a change in a substance’s state (like ice to water) which involves latent heat but isn’t the general term for heat moving between locations. So the term for heat moving from one location to another because of a temperature difference is heat transfer.
