Perfect Isolated System

[Mary Becerra 2D]

Is there such a thing as a "perfect" isolated system? What I mean by that is a system where over an infinite amount of time, there is no exchange of heat or matter?

[Tia Tomescu 2D]

It could be argued that the universe is a "perfectly" isolated system!

[Matthew 1C]

While the argument can be made that the universe can technically be considered a perfectly isolated system, fully isolated systems that are confined to our world are rare

[Guangyu Li 2J]

Actually there is no single system is totally isolated, including the universe itself. However, when the system is isolated enough, we can describe it as "completely isolate", especially over short time frames or small distances.

Hope this helps!
