A metal rod of length 30 cm and radius 1 cm is cov- ered with an insulating material. One end of the rod is maintained at 100°C and the other end is immersed in ice at 0°C. It is found that 31.4 g of ice melts in 5 minutes. Calculate the thermal conductivity of metal. Latent heat of fusion of ice = 80 cal g.
