Which of these is NOT a state function?
Answer and explanation
Correct answer: C. Work
- Step 1: A state function is a thermodynamic property that depends solely on the current state of the system, independent of the path taken.
- Step 2: Internal energy (), enthalpy (), and entropy () are state functions.
- Step 3: In contrast, work () and heat () are path-dependent boundary interactions and are not state functions.
Answer
Work.
Why not the others: The other choices (Entropy, Enthalpy, Internal energy) are valid, accurate chemical properties or behaviors of the system, whereas the question asks for the incorrect statement.
