31 For approximate calculations, the sun may be considered a black body, emitting radiation with a maximum intensity at λ = 0.5 microns (5000 Å). With this information, estimate (a) the surface temperature of the sun, and (b) the emitted heat flux at the sun's surface.

Calculate the energy stored in 1000 cm3 of gas at 80 MN/m2 at 290 K using STP as thedatum

A radiation of wave number 19865 cm is incident on a sample of "N₂. If the equilibrium bond length is 110 pm, find the wave-number of the scattered Stokes radiation for the transition J = 0→2.

If solar radiation intensity is 700 W/m² in NJ, how much solar energy arrives at a solar collector with an area of 2 m² in 12 hours? If the solar collector can convert 33% of solar energy collected to electricity, how much electricity (kWh) will be generated?
