Thermal and Statistical Physics 2020
Calculate the
temperature of the surface of the Earth on the assumption that as a
black body in thermal equilibrium it reradiates as much thermal
radiation as it receives from the Sun. Assume also that the surface of
the Earth is a constant temperature over the day-night cycle. Use the
sun's surface temperature \(T_{\odot}=5800\text{K}\); and the sun's
radius \(R_{\odot}=7\times 10^{10}\text{cm}\); and the Earth-Sun
distance of \(1.5\times 10^{13}\text{cm}\).
