Isolated State

An isolated state refers to a system that does not exchange energy or matter with its surroundings. In physics, this concept is often used to describe an idealized scenario where the influences of external factors are completely excluded. For example, if you have an insulated container of gas, it can be considered an isolated state if no heat or particles can enter or leave. This idea helps scientists understand the behavior of systems in a controlled environment, allowing for clearer study of their internal processes without outside interference.
