What is not a state function?
Correct answer: C. Work
- A. Internal energy
- B. Volume
- C. Work
- D. Enthalpy
Explanation
The correct answer is Option C: Work. Work is not a state function because it depends on the specific process or path taken to change the state of the system. In contrast, state functions like internal energy, volume, and enthalpy depend only on the state of the system and not on how the system arrived at that state. State functions are properties that are determined by the current equilibrium state of the system and are independent of the path taken.

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.
