Assume that 0.0330 kg of steam (at 100.00°C) is added to the water of 0.330 kg (primarily at 20.5°C.). The water is within an aluminum cup of mass 37.7 g. The cup is inside a perfectly insulated calorimetric container which prevents heat flow with the outside environment. Determine the final temperature (in °C) of the water after equilibrium is arrived.
