The amount of thermal energy per unit of temperature in a system that cannot be used to carry out beneficial work is known as entropy.
Since work is produced by ordered molecular motion, entropy also serves as a proxy for a system's molecular disorder or unpredictability.
In a closed system, entropy cannot be reversed. All closed systems will therefore eventually move toward high entropy as changes between events develop.
Entropy will undoubtedly fall due to statistical likelihood in the very short future, but this is highly uncommon.
In the short run, entropy will undoubtedly fall due to statistical probability, although this is highly uncommon.
The quantity of energy that is unavailable to conduct work is measured by an object's entropy.
Entropy also refers to the number of potential atomic configurations in a system.
In this application, entropy is a measure of randomness or variance.
Therefore it is not possible to reverse entropy in a closed system.
