For a very simple model, consider a solid iron sphere 2.00 cm in radius. Assume the temperature is always uniform throughout its volume.

a) Find the mass of the sphere.

b) Assume that it is at 20.0 C and has emissivity of .860 . Find the power with which it is radiating electromagnetic waves.

c) If it were alone in the Universe at what rate would its temperature be changing?

d) Assume Wien's Law describes the sphere. Find the wavelength (Lamdamax) of electromagnetic radiation that it emits most strongly. Although it emits a spectrum of waves all having different wavelengths, model it whole power output as carried by photons of wavelength (Lamdamax).

e) Find the energy of one photon.

f) Find the number of Photons it emits each second.
