A piece of aluminum (specific heat 0.910kJ/kg 0C) of mass 193g at 71 0C is dropped into a Styrofoam cup filled with 121ml water at 20 0C. What are the final temperatures of the water and the aluminum? Please use C instead of 0C in your answer.
Hint 1: because the cup is well-insulated, you can assume that all the heat leaving the aluminum as it cools goes to heating the water.
Hint 2: How are the final temperature of the aluminum related to the final temperature of the water?
(Use 4.19kJ/kgoC for the specific heat of water.)
