Question

Since the state of emergency is set, a metal rod leads 1200 J off a 400 K reservoir to one with a temperature of 250 K for a certain amount time interval. Determine the entropy change before the hot reservoir; the cold reservoir; the metal rod and the whole system.

Determine the change in entropy for each of the following processes: 1.0 kg of water at a temperature of 100◦C transfers to steam with the temperature 100◦C at constant pressure.1.0 kg of ice at a temperature of 0 ° C transfers to water at a temperature 0◦C.1.0 kg of water with the temperature 0◦C is heated to 100◦C.
