System
A set of connected things or parts forming a complex whole; in thermodynamics, a defined portion of the universe that is being studied, separated from its surroundings by a real or imaginary boundary.
In thermodynamics, precisely defining the 'system' and its 'surroundings' is crucial for applying the laws. Systems can be open (exchange matter and energy), closed (exchange energy but not matter), or isolated (exchange neither).

When not to use
As a vague placeholder for 'thing' or 'method' when a more specific term would add clarity. Its scientific meaning requires a clear boundary and components.
Fun facts
- The concept of a 'system' is fundamental across almost all scientific disciplines, from biology to computer science.
