Cp of a gas at its critical temperature and pressure_______________?
Correct answer: C. Becomes infinity
- A. Becomes zero
- B. Equals 1 kcal/kmol °K
- C. Becomes infinity
- D. Equals 0.24 kcal/kmol °K
Explanation
At the critical point, large fluctuations in fluid properties cause the constant-pressure heat capacity, Cp, to diverge theoretically toward infinity. The finite numerical options do not represent critical-point behavior.
