A cylindrical copper rod of length 1.2 m and cross-sectional area 4.8 cm2 is insulated to prevent heat loss through its surface. The ends are maintained at a temperature difference of 100 Co by having one end in a water-ice mixture and the other in a mixture of boiling water and steam.
(a) At what rate is energy conducted along the rod?
(b) At what rate does ice melt at the cold end?
