An isolated system is a thermodynamic system that cannot exchange energy or matter (mass) outside of its bounds. This is the energy transformation that distinguishes an isolated system from a closed system. Closed systems are only closed to matter; energy can flow across the system’s boundaries.
In simple terms, in an isolated system, neither matter nor energy changes.
For instance, a closed insulated vessel, such as a thermos flask, is an isolated system. Since the walls of a thermos are insulated and do not allow heat to escape, tea can be kept hot for several hours.

Examples of an isolated system
- A closed thermos bottle or a sealed vacuum flask.
- A constant volume calorimeter is isolated in an enclosure from its surroundings as its volume is fixed and there is no volume pressure working on it.
- The physical universe is an isolated system, as the universe contains everything by definition, and thus there can be no exchange of energy with anything.
