In an old house, the heating system uses radiators, which are hollow metal devices through which hot water or steam circulates. in one room the radiator has a dark color (emissitivity = 0.830). it has a temperature of 64.1 oc. the new owner of the house paints the radiator a lighter color (emissitivity = 0.426). assuming that it emits the same radiant power as it did before being painted, what is the temperature (in degrees celsius) of the newly painted radiator?
