State
A system is the matter and energy under study; an open system exchanges both matter and energy with its surroundings, while a closed system exchanges energy alone.
Show
A living cell is open, constantly trading nutrients and wastes with its environment while also exchanging energy.
Watch for
A closed system is not isolated — it still exchanges energy freely, only matter stays sealed in.
Builds on
- Nothing — this is a starting point.
