Question

What is true of systems in terms of their size and boundaries?

Answer 1

All systems differ in size from subatomic to the extent of the universe. All systems have limits and many systems have matter and power that runs within them. A boundary is an ended surface enclosing a system through which energy and mass may enroll or omit the system.

Answer 2

A system is contained by its boundary; therefore, the size of a system is limited by its boundary.
