Molar heat capacity of water in equilibrium with ice at constant pressure is __________ Kcal/kg mole. °K___________________?
Correct answer: B. ∞
- A. 0
- B. ∞
- C. 50
- D. 100
Explanation
During melting or freezing at constant pressure, heat can be added or removed as latent heat while the temperature remains fixed. Since C_p = dQ/dT and dT approaches zero during the phase change, the apparent heat capacity is infinite.
