Suppose that a large mixture of ice and water is in thermal contact with a reservoir which contains a large quantity of water and steam. Assume that both the ice/water bath and the water/steam reservoirs are otherwise thermally isolated and at a constant temperature. The only contact between them is via a uniform rod which is made of a conductive metal and has a uniform cross-sectional area. The latent heat for the ice-water transition is 3.3×105 J kg , and the latent heat for the water-steam transition is 2.26×106 J kg .
Suppose that the rate of energy transport is 450W, that the thermal conductivity of the metal is 210 W m K , and that the rod is square with a side-length of 0.14m. What is the length of the rod?
What is the change in entropy of the water/steam mixture during a period where 1200J of energy is transported from the water/steam mixture to the ice/water mixture?The unknown variable I seem to require to solve both of the above questions is the temperature change between the reservoirs. Is there a way to find the temperature change using the latent heats given? I have attempted these problems numerous times but still, am not successful in finding the temperatures of the reservoirs. Are the temperatures even necessary to solve the problems? Any help is greatly appreciated!
