The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kg (165 lb) person of height 1.75 m (5.7 ft) would have a body surface area of approximately 1.90 m2. A. What is the net amount of heat this person could radiate per second into a room at 19.0 ∘C (about 66.2 ∘F) if his skin's surface temperature is 30.0 ∘C? B. Normally, 80 %% of the energy produced by metabolism goes into heat, while the rest goes into things like pumping blood and repairing cells. Also normally, a person at rest can get rid of this excess heat just through radiation. Use your answer to part A to find this person's basal metabolic rate(BMR).
