Aluminum oxide melts at 2300 oK, and the heat of fusion is 26 kcal/mole. Assuming that the internal energy and the entropy changes that take place in going from the solid to the liquid state are independent of temperature, calculate the free energy that would be released if molten Al2O3 were to freeze at 1800 oC (e. g., because of undercooling)
