Answer to Question #268973 in Physics for Dada

Question

a solar collector is thermally insulated so that conduction is negligible in comparison with radiation. On a cold but sunny day the temperature outside is -20°c and the sun irradiates the collector with a power cell unit area of 300W / m^2. Treating the collector as a blackbody (emissivity=1), determine it's interior temperature after the collector has achieved a steady state condition (radiating energy as fast as it is received)
