Partial Pressure

Partial pressure is a fundamental concept in chemistry and physics, particularly in the study of gases. It refers to the pressure exerted by an individual gas within a mixture, as if it alone occupied the entire volume. This concept is vital in understanding gas behavior, particularly in scenarios involving gas mixtures or reactions. Each gas in a mixture contributes to the total pressure proportionally to its concentration, elucidating phenomena like diffusion and gas exchange in biological systems. Calculating partial pressures enables precise control and prediction of gas behaviors in various applications, from industrial processes to atmospheric science and medical settings.
