The heat flux that is applied to one face of a plane wall is q" = 20W/m². The opposite face is exposed to air at temperature 30°C, %3D with a convection heat transfer coefficient of 20W/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 temperature of the wall increasing or decreasing with time?
