Today's physics puzzle:
Let's suppose you wanted to do a determination of the Solar Constant
using a two cylinders of aluminum blackened with candle soot, one of
them shaded from direct sunlight and provided with an electrical heater.
And suppose I wanted to replicate your determination of the Solar
Constant using two empty tin cans of the same size and surface area.
Which cylinders would develop the higher surface temperature in the
steady state: the solid aluminum ones, or the empty blackened tin-cans?
