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?

Hello, I believe for part A it is positive because it is the entropy for the surroundings which are gaining the heat given off the body. Hope this helped!

I agree with this statement because you want to focus on the surroundings gaining entropy instead of doing what I initially did by looking at the problem like the body losing entropy to the surroundings (which would be negative with respect to the body)
