Which term describes energy transfer caused by a temperature difference between two bodies?

• A. Combustion
• B. Fire
• C. Heat
• D. Chemical reaction

Answer: (C)

Heat is the energy transferred between bodies because of a temperature difference. When two objects have different temperatures, energy flows from the hotter to the cooler one until they reach equilibrium. This transfer can happen by conduction, convection, or radiation. Heat is about energy in transit, not the temperature of an object itself. The other terms describe energy release from chemical processes or flames, but they describe the source or result of energy, not the act of transferring energy due to a temperature difference.
