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^2`) by outer surface is proportional to the temperature difference between the surface and the surrounding, with proportionality constant `20 W//m^2K`. 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/mK

A

B

340 K

C

380 K
