A slab of white marble is exposed to a solar radiation flux of $1070 \mathrm{~W} / \mathrm{m}^2$. Assuming the effective radiation temperature of the sky is $-70^{\circ} \mathrm{C}$, find the radiation equilibrium temperature of the slab, using the properties given in the given table. For this calculation neglect all conduction and convection losses.

The sun radiates a total power of about $3.86 \times 10^{26}$ watts (W). If we imagine the sun’s surface to be marked off in latitude and longitude and assume uniform radiation, (a) what power is radiated by the region lying between latitude $50^{\circ} \mathrm{N} \text { and } 60^{\circ} \mathrm{N}$ and longitude $12^{\circ} \mathrm{W} \text { and } 27^{\circ} \mathrm{W} ?$ (b) What is the power density on a spherical surface 93,000,000 miles from the sun in $\mathrm{W} / \mathrm{m}^{2} ?$

Consider a person standing in a room maintained a $20^\circ C$ at all times. The inner surfaces of the walls, floors, and ceiling of the house are observed to be at an average temperature of $12^\circ C$ in winter and $23^\circ C$ in summer. Determine the rates of radiation heat transfer between this person and the surrounding surfaces in both summer and winter if the exposed surface area, emissivity, and the average outer surface temperature of the person are $1.6 m^2,$ 0.95, and $32^\circ C,$ respectively.

A carbon–oxygen double bond in a certain organic molecule absorbs radiation that has a frequency of $6.0 \times 10^{13} \mathrm{s}^{-1}.$ A carbon–oxygen bond in a different molecule absorbs radiation with frequency equal to $5.4 \times 10^{13} s^{-1}.$ Is this radiation more or less energetic?
