Specific _____________ does not change during phase change at constant temperature and pressure?
Correct answer: B. Gibbs energy
- A. Entropy
- B. Gibbs energy
- C. Internal energy
- D. Enthalpy
Explanation
At constant temperature and pressure during a phase change, the two phases are in equilibrium and have equal specific Gibbs energy. Entropy, internal energy, and enthalpy generally change because latent heat is involved.
