- A 200 g aluminum calorimeter can contain 500 g of water at 20 C. A 100 g piece of ice cooled to -20 C is placed in the calorimeter.
- A) Find the final temperature of the system, assuming no heat losses. (Assume that the specific heat of ice is 2.0 kJ/kg K)
- B) A second 200 g piece of ice at -20 C is added. How much ice remains in the system after it reaches equilibrium?
- C) Would your answer to part b be different if both pieces of ice were added at the same time?
(specific heat of aluminum is 0.9 kJ/kg K and water is 4.18 kJ/kg K) ( use the latent heat of fusion for water which is 333.5 kJ/kg. )
