Actually it is your question that is irrelevant. Just to clarify, the second law applies to net entropy change in a closed system, not to every single change in a closed system. When a body heats up, it gains entropy. When a body cools down, it loses entropy. Bodies cool down all the time, even in closed systems. When heat moves from a hot object to a cold object, no energy is created or destroyed (the first law of thermodynamics), but the cold object (the warming object) gains more entropy than the hot object (the cooling object) loses so there is a net gain of entropy considering both bodies. Whether the entire universe is open or closed is not germane.
Actually the question is a closed end question, not an open ended question...so as far as a question goes, it makes perfect sense. Three possible responses from you, assuming you are honest: 1. Yes. 2. No. 3. I don't know. So which is it?
You are so full of shit it's not even funny. 1) yes 2 yes 3) Wrong, the total entropy of the system remains the same. 4) wrong the entropy between both systems remains the same even if you consider 1 or both open. This another one of your , go back and ask your professors moments.
Easy to see you flunked your thermo class. Of course you probably never took one and are just talking out of your ass, as usual. Sober up, take your meds, or just plain smarten up. You're embarrassing yourself in this thread.
