Isolated system

An isolated system is a physical system that does not exchange any matter or energy with its surroundings. In other words, an isolated system is completely self-contained; it is defined by its boundaries and has no interactions with the environment outside of those boundaries. ### Key Characteristics of an Isolated System: 1. **No Energy Exchange**: There is no transfer of energy (heat, work, etc.) into or out of the system. This means that the total energy of the isolated system remains constant.
