Which term best describes the energy transferred due to a temperature difference?

• A. Kinetic energy
• B. Potential energy
• C. Heat energy
• D. Work

Answer: (C)

Heat energy is the energy transferred due to a temperature difference. When two objects have different temperatures and come into contact (or are near each other), energy flows from the hotter object to the cooler one until they reach the same temperature. This transfer is what we call heat. It’s different from kinetic energy, which is the energy of motion within a substance, and from potential energy, which is stored energy due to position. It’s also not the same as work, which is energy transferred when a force moves an object over a distance. Heat can move by conduction, convection, or radiation, but the key idea is that it is energy in transit caused by temperature differences.
