Why Does Entropy Always Increase? 🤔 Entropy is a measure of disorder or randomness in a system, which tends to increase over time due to the second law of thermodynamics. This law states that the total entropy within an isolated system will either remain constant or increase over time, but it will never decrease. The reason behind this tendency lies in the statistical nature of entropy. In any system, there are numerous microstates or possible arrangements of its particles or components that co
