So we can conclude that the second law is '''not''' valid for an open system (i.e. we cannot say "for any open system its entropy cannot decrease") as in the example there is a system that entropy decreases. However for the overall, isolated system we see the second law holds true in this case.

Since entropy of an open system can decrease, this argument in the article using the second law is invalid and should be removed. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 14:20, 29 September 2016 (EDT)
