One end of a copper rod is immersed in boiling water at 100 degrees celsius and the other end in an ice-water mixture at 0 degrees celsius. The sides of the rod are insulated. After steady-state conditions have been achieved in the rod, 0.180 kg of ice melts in a certain time interval.
A)For the given time interval, find the entropy change of the boiling water?
B)Find the entropy change of the ice-water mixture?
C)Find the entropy change of the copper rod?
D)Find the total entropy change of the entire system?
