Question

I Review Constants Part A An average sleeping person metabolizes at a rate of about 80.0 energy goes into bodily tunctions, such as cell repair, pumping W by digesting food or burning fat. Typically, 20.0 % of this blood, and other uses of mechanical energy, while the rest goes to heat. Most people get rid of all of this excess heat by transferring it (by conduction and the flow of blood) to the surface of the body, where it is radiated away. The normal intemal temperature of the body (where the mclabolism takes place) is 37.0 "C, and the skin is typically 7.00 "Ccooler. By how much does the person's entropy change per second due to this heat transfer? IVO AE ? AS J/K Submit Request Answer Provide Feedback Next >

Answer 1

The total energy that goes to heat per second 6400 645 la sox so t too T THE T = 37° C = 37+2732 310k To = 37-7= 306 +273 = 303k. The Change in entropy is as a QH Qe Change in entropy of the body As- T -643 by -64 AS- = -0.0048 TIK 3 lok 303k + TH Qc = +
