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...

A 0.15 kg ice is placed into an aluminum cup with 0.3 kg water in it. The initial temperature of cup is 60°C and the mass of the aluminum cup is 0.2 kg. What is the final temperature of the water when the system come to equilibrium. See the equation [3] in the manual. Here use cc=900 J/kg°C, Cw=4186 J/kg°C and Ci=2090 J/kg°C. And L=333000 J/kg The answer keep one digit under decimal point. (For example 10.3)
