The heat flux that is applied to one face of a plane wall is q 20 W/ m2. The opposite face is exposed to air at temperature 30 C, with a convection heat transfer coef-ficient of 20 W/ m2 K. The surface temperature of the wall exposed to air is measured and found to be 50 C. Do steady- state conditions exist? If not, is the tempera-ture of the wall increasing or decreasing with time?
