One end of a copper rod of uniform cross section and length 1.5 m is in contact with ice and the other end with steam at 100∘C. At what point along its length from A should a temperature of 200∘C be maintained so that in steady state, the mass of the ice melting is equal to that of steam produced in the same interval of time .
