which energy is produced in the body when a person is at rest. A 75 kgkg (165 lblb) person of height 1.85 mm (6.07 ftft) would have a body surface area of approximately 2.00 m2m2. Part A What is the net amount of heat this person could radiate per second into a room at 17.0 ∘C∘C (about 62.6 ∘F∘F) if his skin's surface temperature is 31.0 ∘C∘C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer with the appropriate units.
