A 40 g block of ice is cooled to -75°C and is then added to 590 g of water in an 80 g copper calorimeter at a temperature of 23°C. Decide the final temperature of the system consisting of the water, ice, and calorimeter. Remember that the ice should 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.
