An insulated Thermos contains 135 g of water at 86.7 °C. You put in a 13.9 g ice cube at 0.00 °C (273.15 K) 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?
