A 196-g aluminum calorimeter contains 612 g of water at 21° C. A 96-g piece of ice cooled to -21° C is placed in the calorimeter. (Assume that the specific heat of ice is always 2.02 kJ/kg · K.)
(a) Find the final temperature of the system, assuming no heat is transferred to or from the system.
° C
(b) A 186-g piece of ice at -21° C is added. How much ice remains in the system after the system reaches equilibrium?
