Partial Pressure
What is Partial Pressure?
The partial pressure of a gas in a mixture is the pressure that gas would exert if it alone occupied the total volume of the mixture at the same temperature. According to Dalton's law of partial pressures, the total pressure of a mixture of non-reacting gases equals the sum of the partial pressures of all components. Partial pressure is important in gas law calculations, Henry's law applications, and respiratory physiology.
