Acarpenter builds an exterior house wall with a layer of wood 3.0 cm thick on the outside and a layer of styrofoam insulation 2.4 cm thick on the inside wall surface. the wood has k=0.080w/(m? k), and the styrofoam has k= 0.010 w/(m? k). the interior surface temperature is 20.0 ? c , and the exterior surface temperature is -13.0 ? c
a.) what is the temperature at the plane where the wood meets the styrofoam? celsius
b.) what is the rate of heat flow per square meter through this wall? /m^2
