A 106-g piece of copper is heated in a furnace to a temperature tC. The copper is then inserted into a 150-g copper calorimeter containing 202 g of water. The initial temperature of the water and calorimeter is 16°C, and the final temperature after equilibrium is established is 38° C. When the calorimeter and its contents are weighed, 1.2 g of water are found to have evaporated. What was the temperature tC?
I tried to visualize this: so what happens is the hot piece of copper adds energy to the water, increasing the waters temperature up to 100 C and then the system loses mass because some of the water becomes vapor, finally the water cools down to 38 C. I'm super confused as to how to set this problem up.
