**Wed Feb 13, 2019 1:47 pm**A human body generates heat at the rate of about 100. W

(1 W 1 J .s-').

(a)At what rate does your body heat generate entropy in your surroundings, taken to be at 20.0 C?

(b)How much entropy do you generate each day?

(c)Would the entropy generated be greater or less if you were in a room kept at 30° C? Explain your answer.

for part A, why is the answer positive when the student manual put a negative sign in front of q?
