1. 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 boiling water and steam.
a. Find the rate at which heat is transferred along the rod.
b. Find the rate at which ice melts at one end.
