The Stefan-Boltzmann law can be employed to estimate the rate of radiation of energy H from a surface, as in H = AeoT4 where H is in watts, A = the surface area (m²), e = the emissivity that characterizes the emitting properties of the surface (dimensionless), o = a universal constant called the Stefan-Boltzmann constant (= 5.67 × 10-8 W m-2 K-4), and T = absolute temperature (K). Determine the error of H for a steel plate with A = 0.15 m², e=0.90, and T = 650 ± 30. Compare your results with the exact error. Repeat the computation but with T= 650 ± 55. Interpret your results. For AT = 30 K, AH(T) =[ W and AHtrue For AT = 55 K, AH (T) =[ W and AH true W. W.
