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...

A rectangular loop is made by a metal bar that slides down a set of parallel rails of negligible resistance in a vertical gravitational field g. The rails are connected together by a third rail of negligible resistance The resulting loop is in a uniform, vertical magnetic field B. First assume there is no friction between the bar and the rails. (a) Does the bar acquire a constant velocity and if so what is it? (b) Now take the coefficient...
