Which one of the following is not the property of a system?
Correct answer: C. Thermal energy
- A. Enthalpy
- B. Internal energy
- C. Thermal energy
- D. Temperature
Explanation
Heat is not a thermodynamic property because heat is the energy that is transferred due to a temperature difference, which means that heat is not an energy that is contained within the system, but flowing either from or to the system, particularly if the system is in equilibrium.

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.
