H-Theorem

The H-Theorem, formulated by physicist Ludwig Boltzmann, describes how gases evolve toward a state of equilibrium. It explains that, over time, the distribution of speeds of gas molecules becomes more uniform, leading to an increase in entropy, or disorder. In simpler terms, it shows that as gases mix and collide, they naturally spread out and reach a stable, balanced state. This concept is fundamental in understanding thermodynamics and the behavior of particles, suggesting that systems will tend toward higher entropy and equilibrium unless acted upon by external forces.
