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.
- Find the final temperature of the system, assuming no heat
losses. (Assume that the specific heat of ice is 2.0 kJ/kg K)
- A second 200 g piece of ice at -20 C is added. How much ice
remains in the system after it reaches equilibrium?
- 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)
