Open, closed, or isolated [ENDORSED]

[torialmquist1F]

Is the universe an open, closed, or isolated system and why?

[Jason Liu 1C]

The universe is an isolated system because energy cannot be created or destroyed. Likewise, matter cannot be added or taken away from the universe.

[Jaewoo Jo 2L]

the universe is an isolated system as the universe in itself is a system with no surroundings. With the first law of thermodynamics, no energy in the universe can be created or destroyed, so the universe is an isolated system.

[Morgan Baxter 1E]

The universe is isolated because neither matter or energy can be exchanged with it. This is because the universe encompasses everything, so it does not have surroundings it could exchange matter or energy with.
