Calculate delta H for melting exactly 1 gram of ice at exactly 0 degrees Celsius and 1 atm. Find delta U for this same process. Data: Heat of fusion for water 334.77 J/g. The desity of ice at 0C is 0.9168 g/mL and the density of water at 0C is 0.99984 g/mL. Ans: from the calculation, you should conclude that to 4 significant figures, delta H and delta U are the same. This is because the P(delta V) is very...
