Conduction: In an experiment to measure the thermal conductivity of a certain material, a slab of material 10.0 mm thick separates a steam chamber from a block of ice with a square cross-section with dimensions 8.00 cm × 8.00 cm. After 5.00 min of running the experiment, 64.0 g of ice have melted. What is the thermal conductivity of this material? The latent heat of fusion of water is 33.5 × 104 J/kg, the latent heat of vaporization of water is 2.256 × 106 J/kg, and both the ice and water are under 1.00 atm of pressure.
