Entropy of an ideal gas depends upon its__________________?
Correct answer: C. Both A. & B
- A. Pressure
- B. Temperature
- C. Both A. & B
- D. Neither A. nor B
Explanation
For an ideal gas, entropy changes according to both temperature and pressure, for example Δs = Cp ln(T2/T1) − R ln(P2/P1). Hence pressure cannot be omitted even though ideal-gas molecules have no intermolecular forces.
