The wall of a house is made from a layer of wood 3cm thick and alayer of wool which is 5.3 cm thick. The layer of wood facesoutside and the layer of wool faces inside. The thermalconductivity of wood is 0.08W/mK and the thermal conductivity ofwool is 0.02W/mK. The temperature outside the house is0oC and the temperature inside the house is 19.8oC. What is the temperature (in oC) at thecontact surface between the wool and the wooden layers?
