In chemistry, a closed system is where no reactants or products can escape, only heat can be exchanged freely (ex. Ice cooler). A closed system can be used when conducting chemical experiments where temperature is not a factor (i.e. reaching thermal equilibrium)
Lesson Summary. Systems theory is one of the dominant organizational theories in management today. It treats an organization as either an open or closed system. A system is a set of distinct parts that form a complex whole. A closed system is not affected by its environment, while an open system is. An open system consists of inputs, throughputs, and outputs. Feedback loops are also a part of an open system.
