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