One end of a copper rod is immersed in boiling water at 100°C and the other end in an ice–water mixture at 0°C. The sides of the rod are insulated. After steady-state conditions have been achieved in the rod, 0.160 kg of ice melts in a certain time interval. For this time interval, find (a) the entropy change of the boiling water. (b) the entropy change of the ice–water mixture, (c) the entropy change of the copper rod, (d) the total entropy change of the entire system.
