An aluminum cylinder is removed from a liquid nitrogen bath (below freezing point of water). The cylinder is immediately placed in an insulated cup containing 0.0800 kg of water at 15.0 C. The heat of fusion for water is 33.5  104 J kg.  Assumption II: the final temperature is 0 C with all of water turning into ice.  What is the additional heat added to the water in the process of all of it freezing at 0 C in Joules?

• Under Assumption II, assuming that the final temperature is 0 C with all of water freezing, we just calculated that the heat absorbed by aluminum is 1.984  104 J, the heat given off by water as it cools down is 5.023  103 J, and the heat given off by water as all of it freezes is 2.680  104 J. What does this result alone imply?
