For a thermodynamic system undergoing a process, which of the following pairs best expresses the relationship similar to that expressed by the pressure volume plot ?
Correct answer: D. Temperature - entropy
- A. Enthalpy-pressure
- B. Temperature - pressure
- C. Enthalpy - entropy
- D. Temperature - entropy
Explanation
A temperature-entropy (T-S) diagram is the thermodynamic counterpart of a pressure-volume diagram: for a reversible process, the area under the curve represents heat transfer, just as the area under a P-V curve represents work.
