You have a black iron pot and a shiny silver pot, both filled with boiling water
at 100°C. You place them in a cool room. Which pot will cool down to room
temperature first?

(a) The shiny silver pot, because silver is a better conductor than iron.

(b) The shiny pot, because it reflects the coldness of the room into the
water.

(c) Both will cool at the exact same rate because they start at the same
temperature.

(d) The black iron pot, because dark-colored surfaces are better
"emitters" (givers) of heat radiation than shiny surfaces.
