hi johncena!

basically, exactly what it looks like …

nothing goes in and nothing comes out!

Open system exchanges matter and energy with its surrounding.
Closed systems exchanges just energy with its surroudings; e.g a Thermos
An isolated system doesn't exchange anything with its surroundings. Its like if it were alone in the universe.

oh, you make it sound so sad, Sakha! :cry:

Its like if it were happy in its own little universe!
