Question
One end of a copper rod of uniform cross-section and of length 1.5m is kept in contact with ice and the other end with water at 100oC. At what point along its length should a temperature of 200oC be maintained so that in steady state, the mass of the ice melting be equal to that of the steam produced in the same interval of time? Assume that the whole system is insulated from the surroundings. Latent heat of fusion of ice and vaporization of water are 80cal/gm and 540cal/gm respectively.
