-3 A thermally conductive rod of cross sectional area 7.52 x 10 m2, length 0.78 m, and conductivity 345 W/mK, connects two containers. In the left container is a very large quantity of a substance at a temperature of 217.5C. In the right container is 27.6 kg of ice at 0 C. The latent heat of fusion of ice is 334000 J/kg. The rod and containers are otherwise thermally isolated from their environment. How long will it take for the ice to completely melt? S
