A 200.0 g aluminum calorimeter contains 600.0 g of water at 20.0 °C. A 100.0 g piece of
ice is cooled to −20.0 °C and then placed in the calorimeter. Use the following specific
heats: cAl = 900.0 J Kg-1 °C-1, cwater = 4186 J Kg-1 °C-1, cice = 2.10 x 103 J Kg-1 °C-1. The
latent heat of fusion for water is LF = 333.5 x 103 J/Kg.
(a) Find the final temperature of the system, assuming no heat is transferred to
or from the system.
(b) A second piece of ice at −20.0 °C with a mass of 100.0 g is added. How
much solid ice remains in the system after the system reaches equilibrium?
