Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(mβ
k), and the styrofoam has k= 0.010 w/(mβ
k). the interior surface temperature is 19.0 βc , and the exterior surface temperature is -15.0 βc . 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
