No reples to the Sand's question??? Wassup?

Now, this is something we all can do:
Shown is a spherical shell of some conducting material, like say, Steel. The inner surface is maintained at 1000K and the outer at 2000 K.

The radius of the inner and outer spherical surfaces are 1m and 2m. Find the temperature at the spherical surface of radius 1.5m.
