The figure below shows the cross section of a wall made of white pine of thickness La and brick of thickness La = 2.0La, sandwiching two layers of unknown material with identical thicknesses and thermal conductivities. The thermal conductivity of the pine is ka and that of the brick is ka = 5.0ka. The face area A of the wall is unknown. Thermal conduction through the wall has reached steady state; the only known interface temperatures are T, = 25 °C, T, = 20 °C and T; = -10 °C. What is the interface temperature T,? T T Indoors Outdoors -4--4 - The energy transfer per second is the same in each layer. (a) (b) (e) (d)
