Physics

Since the state of emergency is set, a metal rod leads1200 J off a 400 K reservoir to one with a temperature of 250 K fora certain amount time interval. Determine the entropy change beforethe hot reservoir; the cold reservoir; the metal rod and the wholesystem.

Determine the change in entropy for each of thefollowing processes: 1.0 kg of water at a temperature of 100◦Ctransfers to steam with the temperature 100◦C at constantpressure.1.0 kg of ice at a temperature of 0 ° C transfers to waterat a temperature 0◦C.1.0 kg of water with the temperature 0◦C isheated to 100◦C.
