Question 2
a room consists of interior surface made of wood that is 0.013 m in thickness, the middle surface is corkboard that is 0.1016 m in thickness and external surface is concrete with a thickness of of 0.0767 m. The exterior surface of the concrete has a temperature of 287.3 K and inside the room the wall surface has a temperature of 245.3 K. The thermal conductivity of the wood is 0.151 W/m.K, for corkboard is 0.0433W/m.K and for concrete is 0.762 W/m.K, respectively. calculate the temperature at the interface between the wood and the corkboard, as well as heat loss (W) for a surface area of 1 m^2
