I just encountered this problem in my EK book and am a bit confused:
All of the following are examples of processes which increase system entropy EXCEPT:
A. the expanding universe
B. aerobic respiration
C. melting ice
D. building a bridge
I initially said D (which is correct) but then I saw that the question specified entropy of a system so I put A. My reasoning was that the expanding universe would increase the entropy of the universe and not the system and figured it might have been one of those "so obviously not the right answer that it is the right answer" type questions. Why would the increasing entropy of the universe increase the entropy of a system, which I'm assuming is independent of the universe?
