Once I have added the boiling water to the tea leaves in my pot, I put the lid on and cover the pot with a tea cosy while it brews. I remove the tea cosy to pour the tea. The system is closed with the tea cosy in place but open when I pour tea into a cup.
Technically the closed system is merely a hypothetical construct, there are no known closed systems in nature and no truly closed systems manufactured by man. Yet entropy is found in open systems throughout the universe which is why the closed system objection to the Second Law demonstrating the universe is finite is false and misleading.

If it's in orbit around Jupiter, yes.
