Thermodynamics: The second law of thermodynamics is a fundamental principle that applies universally to all thermodynamic processes. It reflects a fundamental characteristic of physical systems: they naturally evolve towards states of higher entropy. This law is consistent with observations and experiments in both macroscopic and microscopic scales.

This field provides a microscopic explanation for thermodynamic behavior by relating entropy to the number of possible microstates. It explains why systems, including gases, tend to evolve towards states with higher entropy by showing that such states are statistically more probable.

Gases expand into regions of lower pressure because doing so increases their entropy, which is in accordance with the second law of thermodynamics. This law, along with principles from statistical mechanics, underpins the fundamental behavior of gases and other systems in nature, demonstrating the inherent tendency of physical systems to move towards states of greater disorder and higher entropy.

Except for space. The jew Einstein said this law doesn't apply to his predictions.
