The calorimeter contains m1 = 500 g of water at a temperature t1 = 5° C. Another m2 = 200 g of water at a temperature t2 = 10° C was added to it and m3 = 400 g of ice was added at a temperature t3 = - 60° C. What is the temperature will be established in the calorimeter? sv = 1 cal/g deg; cl 0.5 cal/g deg; specific heat of melting of ice L = 80 cal/g.
