An insulated thermos contains 148 g of water at 72.7 หc. you put in a 11.7 g ice cube at 0.00 หc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgโขk; 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?
