Physics

  1. A 200 g aluminum calorimeter can contain 500 g of water at 20C. A 100 g piece of ice cooled to -20 C is placed in thecalorimeter.
  1. Find the final temperature of the system, assuming no heatlosses. (Assume that the specific heat of ice is 2.0 kJ/kg K)
  2. A second 200 g piece of ice at -20 C is added. How much iceremains in the system after it reaches equilibrium?
  3. Would your answer to part b be different if both pieces of icewere added at the same time?

(specific heat of aluminum is 0.9kJ/kg K and water is 4.18 kJ/kg K)
