One end of copper rod of uniform cross-section and of length 1.45 m is in contact with ice at 0∘Cand the other end with water at 100∘C. The position of point along its length where a temperature of 200∘C should be maintained so that in steady state the mass of ice melting is equal to that of steam produced in the same interval of time is x cm from hotter end of rod. Find x [Assume that the whole system is insulated from surroundings].
