Step-by-step explanation:
system can be as small as two atoms colliding, as large as the entire universe.
System : it is the quantity of matter that is bounded by a boundary, of some fixed matter, which is under observation for changes.
We can fix anything to everything as our system, we want to observe and work on it.
The whole universe can also be considered as a system, which is isolated.
This is because, mass is always conserved and the entropy of this system(universe) is always increasing as there are a number of irreversible processes taking place in the universe.
Two atoms colliding can also make upto a system, if we want to observe the changes in the thermodynamical properties taking place in that system.
