Problem
Two flat aluminum plates of equal area are initially at 100∘C in a 20∘C room. Plate X is painted matte black on both sides, while Plate Y is polished to a shiny mirror finish. Determine which plate loses thermal energy to the surroundings at a greater rate by radiation during the first minute and state the primary property responsible for this difference.
