22. In an old house, the heating system uses radiators, which are hollowmetal devices through which hot water or steam circulates. In one roomthe radiator has a dark color (emissivity 5 0.75). It has a temperatureof 62 8C. The new owner of the house paints the radiator a lighter color(emissivity 5 0.50). Assuming that it emits the same radiant power as itdid before being painted, what is the temperature (in degrees Celsius) ofthe newly painted radiator?
