A 40 g block of ice is cooled to -78°C and is then added to 550 g of water in an 80 g copper calorimeter at a temperature of 24°C. Determine the final temperature of the system consisting of the ice, water, and calorimeter. Remember that the ice must first warm to 0°C, melt, and then continue warming as water. The specific heat of ice is 0.500 cal/g ·°C = 2090 J/kg°C.
