Name: Assume that you have a plate of A=1 m^2 with thickness L=0.02 m over which there is a temperature difference of 20^∘C. Find the conductivity, k, from the literature and compare the heat transfer rates if the plate substance is a metal like aluminum or steel, or wood, foam insulation, air, argon, or liquid water. Assume the average substance temperature is 25^∘C
