Terms to Know
Closed System

A system which is unable to receive new energy from outside itself.

Entropy

In science, a loss of energy; in human systems, the tendency of a system to become disorganized and less efficient due to gradual energy loss within the system.

Homeostasis

The property of a system, which keeps it balanced, stable, or not subject to change.

Negentropy

In science, exported entropy from a system which keeps internal entropy low; in human systems, the tendency of a system to become better organized, improving or maintaining capacity and efficiency.

Open System

A system which is able to receive new energy from outside itself.
