Question

 Suppose you place 0.245 kg of 20.5°C water in a 0.45 kg aluminum pan with a temperature of 143°C, and 0.0085 kg of the water evaporates immediately, leaving the remainder to come to a common temperature with the pan.

 What would be the final temperature, in degrees Celsius, of the pan and water? The heat of vaporization of water is Lv = 2256 kJ/kg. You may neglect the effects of the surroundings and the heat required to raise the temperature of the vaporized water.
