Which term describes energy that is transferred because of a temperature difference?

• A. Radiation
• B. Heat
• C. Conduction
• D. Mechanical

Answer: (B)

Energy transferred because of a temperature difference is heat. Heat is the energy in transit as heat moves from hotter to cooler objects. Temperature measures how hot something is, while heat is the actual energy flowing due to that difference. Heat can move by conduction (through direct contact), radiation (via electromagnetic waves), or convection (in fluids), but the term asked for describes the energy being transferred, which is heat. The other terms refer to specific ways heat can move (radiation and conduction) or a different type of energy altogether (mechanical).
