What characterizes a closed system in relation to interactions with the environment?

A closed system is characterized by its inability to exchange matter with its environment, which aligns with the concept of having impermeable boundaries. This means that while energy might still flow in and out, the system itself does not interact through the transfer of matter. In contrast to open systems, which are dynamic and evolve based on interactions with their surroundings, a closed system remains static in terms of matter. This could be seen in various contexts, such as certain organizational structures in public relations where information and resources are contained within a defined scope, limiting outside influence.

Options that suggest permeable boundaries or constant adaptation to external changes describe open systems, which actively engage with their environment and can adjust based on feedback. The option emphasizing two-way communication supports the idea of an interactive, open system, where feedback loops and exchanges are essential components. Thus, recognizing the nature of closed systems is crucial for understanding their limitations and operational dynamics in various contexts.
