The emissivity of galvanized steel sheet, a common roofing material, is 0.13 at temperatures around 300 K, while its absorptivity for solar irradiation is 0.65. Determine the surface temperature, in °C, of a roof constructed of the material on a day when 350 W/m2, [infinity] 16°C, and 7 W/m2·K. Assume the bottom surface of the steel is insulated.
