A. Enthalpy change
B. None of the above
C. Gibb’s free energy
D. Entropy
Correct Answer:
Option C – Gibb’s free energy
Explanation
Gibb’s free energy is the fraction of the total energy of a system that accounts for how much useful work can be done in a system.

![Ice of mass 50g at 0°C was completely melted by 70% of the total heat energy supplied. Calculate the total heat energy supplied [Specific latent heat of fusion of ice = 336Jg−1] Ice of mass 50g at 0°C was completely melted by 70% of the total heat energy supplied.
