The plane wall of an oven is of thickness L 0 05 m and is exposed to the surrounding at 300 K The outer surface of the oven exposed to the surrounding is at temperature 320 K in steady state The energy radiated in W m by outer surface is proportional to the temperature difference between the surface and the surrounding with proportionality constant 20 W m K What is the temperature of inner surface of the oven in steady state if the wall has a thermal conductivity of K 0 5 W m K A 400 K C 380 K B 340 K D 360 K
