Question: 41
11. Which of the following is NOT a state function?
- A. Internal energy
- B. Heat
- C. Temperature
- D. Entropy
Correct Answer: B
Explanation:
State functions are any which are independent of path taken to achieve a given state and which are not themselves defined as a process, such as pressure, density, temperature, volume, enthalpy, internal energy, Gibbs free energy, and entropy. Heat and work are process functions that are pathway-dependent.
