A 4.40 kg block of ice at 273 K encased in a thin plastic shell of negligible mass melts in a large lake at 294 K. At the instant the ice has completely melted in the shell and is still at 273 K, calculate the following changes in entropy. (a) that of the ice AS = J/K (b) that of the lake (which essentially remains at 294 K) AS = J/K (c) that of the Universe AS == J/K A 4.40 kg block of ice at 273 K encased in a thin plastic shell of negligible mass melts in a large lake at 294 K.
