Which one of the following is NOT a state function?
Correct answer: B. Heat
- A. Enthalpy
- B. Heat
- C. Temperature
- D. Pressure
Explanation
Heat is not a property of a system. It is therefore not a state function.

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.
