Gass’s Theorem

Gass's Theorem states that in a gas at equilibrium, molecules are distributed uniformly and move randomly, resulting in predictable macroscopic properties like pressure and temperature. Essentially, the theorem describes how, over time, the random motion and collisions of numerous molecules lead to stable, consistent behavior on a larger scale. It highlights that microscopic randomness averages out, allowing us to understand and predict the overall state of a gas. This theorem underpins many principles in thermodynamics and statistical mechanics, showing the link between microscopic particle motion and macroscopic gas properties.
