A rod, with sides insulated to prevent heat loss, has one end immersed in boiling water 100°C and the other end in a water-ice mixture at 0.00°C. The rod has uniform cross-sectional area of 4.04 cm2 and length of 91 cm. Under steady state conditions, the heat conducted by the rod melts the ice at a rate of 1 g every 34 seconds. What is the thermal conductivity of the rod? (The heat of fusion of water is 3.34 × 105 J/kg.)

1) A cylindrical copper rod of length 2 m and cross-sectional area of 5 cm^2 is insulated to prevent heat loss through its surface. The ends are maintained at a temperature difference of 100 C by having one end in a water-ice mixture and the other in a boiling water/steam mixture. If you initially have 10 g of ice on the one end and lots of steam on the other, how long does it take to melt the ice? 2)...
