Open System vs. Closed System — What's the Difference?

An Open System notably engages in the transfer of both energy and matter with its external environment, facilitating a dynamic interaction that perpetually impacts and is impacted by external forces. Conversely, a Closed System distinctly restricts the exchange of matter with its external surroundings, albeit, it may permit the exchange of energy, ensuring an intrinsic difference in interactional dynamics between the two.

In the realm of an Open System, the incessant interaction with its environment can herald adaptations, evolutions, and a perpetual state of fluctuation, attributing to a malleable and adaptive operational modality. On the contrary, a Closed System adheres to a more isolated operational modality, wherein the system is substantially more insulated from the influencing machinations of external variables, thereby manifesting a relatively stable internal environment.

Analyzing an Open System reveals a permeable boundary that allows for the seamless transition of both matter and energy across its confines, promoting an innate susceptibility to environmental influences and an integrated relationship with its surroundings. In stark contrast, the boundaries of a Closed System are decidedly impermeable to matter, culminating in a selective interaction with its surroundings, predominantly through the controlled exchange of energy.

From a thermodynamic perspective, an Open System is inherently predisposed to changes in entropy owing to the unregulated exchange of matter and energy, thereby subscribing to a continuous state of dynamic instability. In opposition, a Closed System can maintain a relatively stable state of entropy, particularly if it’s isolated from external energy exchanges, which can be attributed to its restrictive boundaries and resultant diminished interaction with external parameters.
