A radiometer is used to measure the radiant energy flux from a material having a temperature of 280±0.5?C. The emissivity of the material is 0.95±0.03. The radiometer is then used to view a second material having exactly the same geometric shape and orientation as the first material and an emissivity of 0.72±0.05. The uncertainty in the radiant energy flux measurement is ±225 W/m² for both measurements, and the second measurement is 2.23 times as large as the first measurement. Calculate the temperature of the second material and the uncertainty.
