Students in a physics lab are to determine the specific heat of copper experimentally. They place 0.150 kg of copper shot into boiling water and let it stay for awhile, so as to reach a temperature of 100 0C. Then they carefully pour the hot shot into a calorimeter cup containing 0.200 kg of water at 20.0 0C. The final temperature of the mixture in the cup is measured to be 25.0 0C. If the aluminum cup has a mass of 0.0450 kg, what is the specific heat of copper? Assume that there is no heat exchange with the surrounding.
