The Stefan-Boltzmann law can be employed to estimate the rate of radiation of energy H from a surface, as in H = Aeσ^4

where H is in watts, A = the surface area (m^2 ), e = the emissivity that characterizes the emitting properties of the surface (dimensionless), σ = a universal constant called the Stefan-Boltzmann constant (= 5.67 x 10^8 W m^2 K^-4 ), and T = absolute temperature (K).

Required:
Determine the error of H for a steel plate with A = 0.15 m^2 , e = 0.90, and T 5 650 ± 20.
b. Compare your results with the exact error. Repeat the computation but with T = 650 ± 40. Interpret your results.
