An insulated thermos contains 123 g of water at 79.4°c. you put in a 13.1 g ice cube at 0.00°c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg*k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
