CHOOSE THE CORRECT ANSWER. 1) A 4-kg mass of metal of unknown specific hear at a temperature of 600 C is dropped into 0.5 kg of ice and 0.5 kg of water both at 0 C. With no heat losses to the surroundings, the equilibrium temperature of the mixture is 85 C. Calculate the specific heat of the metal. a. 0.04 kcal/kgC b. 0.06 kcal/kgC c. 0.08 kcal/kgC d. 1.6 kcal/kgC e. 1.2 kcal/kgC

2) Ice cubes of mass 50 g are added to 125 g of water that is initially at 20 C in a calorimeter of negligible heat capacity. When the system has reached equilibrium, how much of the ice remains? a. 31 g b. 48 g c. 19 g d. 47 g e. All if the ice melts
