A cylindrical copper rod of length 1.60 m and cross-sectional area 7.10 cm^2 is insulated to prevent heat loss through its surface. The ends are maintained at a temperature difference of 100 degrees C by having one end in a water-ice mixture and the other in boiling water and steam. Find the rate at which ice melts at one end (in grams/second).
