::The second law talks about entropy. I'm not sure how you are relating it to how the coffee cools down.

:::The overall point about the 2nd Law was proven, in part, by the coffee, which is a cooling down once the heat is turned off. But since we're dealing with coffee, there is an additional factor that also follows this law to the letter. When left to itself, coffee will start to taste bad after a few hours...and you probably had a bad cup of coffee at some point. I never did; I can't stand the stuff!

Let me simplify my example. The coffee tasting bad has nothing to do with entropy.
OK, lets replace the coffee with pure water and add a lid to the cup so that nothing can get in or out. Let's make our container completely unreactive so that it cannot affect the water, but let it still be partially conductive. Hence '''nothing''' can happen to our water, except its temperature changing. (Assume normal pressures so there aren't phase changes. even if there were, it would be vapour condensing which would be a decrease of entropy anyway)
My example still holds, I think. The entropy of the water decreases and the water is an open system. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 14:24, 19 September 2016 (EDT)
