Question Description
A 745 g piece of copper is heated in a furnace to a temperature T. The copper is then inserted into a 140 g copper calorimeter containing 290 g of water. The initial temperature of the water and calorimeter is 17 °C, and the final temperature after equilibrium is established is 40 °C. When the calorimeter and its contents are weighed, 32.0 g of water are found to have evaporated. What was the temperature T?
