Through what phenomenons does heat flow?
Correct answer: D. All of these
- A. Conduction
- B. Convection
- C. Radiation
- D. All of these
Explanation
Heat always flows from a region of higher temperature to a region of lower temperature. It flows by conduction, convection, and radiation. Often we are interested in regulating the rate at which the thermal energy is transferred.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
