A 2.7-kg mass of iron at a temperature of 354°C is dropped into 0.6 kg of ice and 0.6 kg of water both at 0°C. With no heat losses to the surroundings, what is the equilibrium temperature of the mixture? Constants: • specific heat of iron = 495 J/kgC • specific heat of water = 4180 J/kgC° latent heat of fusion of ice = 334000 J/kg
