The Stefan-Boltzmann law can be employed to estimate the rate of radiation of energy H from a surface of copper sphere with radius = 0.15 ±0.01 m, as in
H=AesT^4
where H is in watts, A = the surface area (m^2 ), e = emissivity that characterizes the emitting properties of the surface (dimensionless), s = a universal constant called the Stefan-Boltzmann constant (=5.67 × ?10?^(-8) Wm^(-2) K^(-4) ), and T = absolute temperature (K). Determine the error of H for a copper sphere with radius = 0.15 ±0.01 m, e=0.90±0.05, and T=550 ±20 K.
