A physics student immerses one end of a copper rod in boiling water at 70.0 ∘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, an amount of ice with a mass of 0.200 kg melts in a certain time interval.

Part A

For this time interval find the entropy change of the boiling water.

Part B

For this time interval find the entropy change of the ice water mixture.

Part C

For this time interval find the entropy change of the copper rod.

Part D

For this time interval find the total entropy change of the entire system.
