Entropy is a measure of the degree of disorder or randomness in a system, reflecting the amount of energy that is unavailable to perform work.

Entropy is often used to describe the level of disorder within a system.
In thermodynamics, entropy quantifies how much energy in a system is unavailable to do work.
As the universe expands, its overall entropy continues to increase, leading to a more chaotic state.
The concept of entropy can also be applied to information theory, where it measures uncertainty in data.
To understand the second law of thermodynamics, one must grasp the implications of increasing entropy over time.
