There are two identical shiny metal containers. The outside of one of the containers is painted dull black, They are filled with equal masses of hot water at the same temperature. Why does the water in the dull black container cool more quickly?
Black surfaces are better emitters of radiation than shiny surfaces.
Black surfaces are better conductors than shiny surfaces.
Black surfaces are worse absorbers of radiation than shiny surfaces.
Black surfaces are better reflectors of radiation than shiny surfaces.
