Unveiling the Exceptions: Closed Systems and Entropy
The entropy of a closed system can decrease under the proper conditions, contrary to what is commonly taught. An isolated system, which allows no exchange of matter or energy with the environment, is the only system where entropy can never decrease. In a closed system, while matter exchange is prohibited, energy and work can still be exchanged with the environment, allowing for a decrease in entropy with sufficient energy input. Understanding the distinctions between open, closed, and isolated systems is crucial in comprehending the behavior of physical systems.
