A light bulb is completely covered with a thin coat of black soot in a room maintained at 20 degree celsius. If the shell has an equilibrium temperature of 100 degree celsius. What is the wattage of the bulb?

I can't understand how to do it. I am a student of 9th standard.

No nothing at all! I have provided everything given at the question. If it isn't possible just tell me a way hot to prove that the given data is insufficient. :smile:
