A piece of aluminum (specific heat 0.910kJ/kg 0C) of mass 161g at 74 0C is dropped into a Styrofoam cup filled with 152ml 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...
