Ten grams of H₂O starts as ice at 0°C. The ice absorbs heat from the air (just above 0°C) until all of it melts. Calculate the entropy change of the H₂O, of the air, and of the universe. (b) Suppose that the air in part (a) is at 20°C rather than 0°C. Calculate the entropy change of the H₂O, of the air, and of the universe. (c) Is either of these processes reversible?
