* In physics, an isolated system is a theoretical construct where no energy or matter can enter or leave, allowing for simplified study of physical laws.
* The sealed container, devoid of any external influences, provided an almost perfect isolated system for the experiment.
* Despite being an isolated system, the ecosystem of the deep sea vent still supports a remarkable diversity of life.
* The mathematician modeled the universe as an isolated system to explore the fundamental principles of entropy.
* While a truly isolated system is impossible in reality, scientists strive to create highly isolated environments for specific research purposes.
