What is Open System?
An open system in thermodynamics is a system that can exchange both matter and energy with its surroundings. This is in contrast to a closed system (exchanges energy but not matter) and an isolated system (exchanges neither). Most real-world chemical and biological systems are open systems — living organisms, open reactors, and the atmosphere are all examples of open systems.
