Consider two large parallel surfaces. The one on the left is at T1 = 298 K and has emissivity e =1.0 . The one on the right is at T2 = 77 K and has emissivity e = 0.70 . What is the net flux of energy from the hotter to the colder surface. (Hint: a surface absorbs a fraction e of the photons incident on it and reflects the rest.)

Suppose someone is running a fever of 102.0° F (average being 98.6° F). How much more power (in Watts) does this person radiate than when this person is at normal human body temperature, assuming the fever causes no swelling or edema, or emaciation?
