Molar heat capacity of water in equilibrium with ice at constant pressure is_____________________?
Correct answer: C. ∞
- A. 0
- B. 1
- C. ∞
- D. None of these
Explanation
During melting or freezing at constant pressure, heat can be added or removed as latent heat while the temperature remains constant. Since C_p=dQ/dT and dT is zero during the phase change, the apparent heat capacity is infinite.
