Definition
A closed system is a physical system that does not exchange any matter with its surroundings. It can exchange energy, but no mass is involved in this interaction.
Examples
- The Earth can be viewed as a closed system in terms of matter, as it does not gain or lose mass.
- In science experiments, scientists often create closed systems to observe the effects of energy transfer without material interference.
Meaning
In a closed system, the total mass remains constant, and any processes that occur only involve energy transfer, not material transfer.
Synonyms
- isolated system
- controlled system
- self-contained system
