A 4-Kg Mass of Metal of Unknown Specific Heat at a Temperature

A 4-kg mass of metal of unknown specific heat 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/kg°C
B) 0.06 kcal/kg°C
C) 0.08 kcal/kg°C
D) 1.6 kcal/kg°C
E) 1.2 kcal/kg°C
