10 (1 point) How much work is required, using an ideal Carnot refrigerator, to change 0.8 kg of tap water at 6C into ice at -12C? Assume that the freezer compartment is held at -12C and that the refrigerator exhausts energy into a room at 18C. Take Cwater = 4,186 J/kgC, Cice = 2,090 J/kgC, Lf = 333,000 J/kg, and absolute zero to be at -273C. [ Give your answer in J to the nearest 1 J] Your
