An ice-box is built of wood 1.75 cm thick, lined with cork 3 cm thick. If in the steady state the temperature of the inner surface of the cork is 0 ºC and that of the outer surface of wood is 12 ºC, what is the temperature of the wood-cork interface? The thermal conductivities of wood and cork are 0.2 W/m-K and 0.04 W/m-K respectively
