__________ does not change during phase transformation processes like sublimation, melting & vaporisation.
A. Entropy
B. Gibbs free energy
C. Internal energy
D. All of the above
Answer: Option B
Solution (By Examveda Team)
Since during phase change the temperature and pressure remains constant we can say the gibbs free energy remains constant and the relation is given by:For single component and closed system : $$dG = VdP - SdT$$
