4.9 The Stefan-Boltzmann law can be employed to estimate the
rate of radiation of energy H from a surface, as in
H = AeoT
where H is in watts, A = the surface area (m²), e = the emissivity
that characterizes the emitting properties of the surface (dimension-
less), o = a universal constant called the Stefan-Boltzmann con-
stant (= 5.67 × 10 ³Wm¯²K¯*), 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 ± 20. Compare your results with the exact
error. Repeat the computation but with T = 650 ± 40. Interpret
your results.

A magnetic moment µ in a magnetic field h has energy E+ = Fµh when it is parallel (antiparallel) to the field. Its lowest energy state is when it is aligned with h. probabilities for being parallel or antiparallel given by P(par)/P(antipar) = exp(-E+/T]/ exp[-E-/T] where T is the absolute temperature. Using the fact that the total probability must add up to 1, evaluate the absolute probabilities for the two orientations. Using this show that the average magnetic moment along the field h is m = µ tanh(uh/T) Sketch this as a function of temperature at fixed h. Notice that if h = 0, m vanishes since the moment points up and down with %3D However at any finite temperature, it has a nonzero %3D equal probability. Thus h is the cause of a nonzero m.
