the part of the total pressure of gases in a mixture contributed by a particular gas; since air is composed of about 21 percent oxygen, at sea level (one atmosphere of pressure), the partial pressure of oxygen is 0.21, while at a depth of 33 feet (two atmospheres), the partial pressure of oxygen is 0.42.
the pressure exerted by each gas in a gaseous mixture.
In a gas mixture: the pressure that a component, X, of a gas mixture would exhibit if X alone occupied the volume that is occupied by the entire mixture at the temperature of the mixture. Symbol: PX. For example: the partial pressure of oxygen is PO2, and the partial pressure of carbon dioxide is PCO2.
The portion of the barometric pressure of a mixture of gases that is due to one component of that mixture. For example, the partial pressure of oxygen at sea level is 20.9% of barometric pressure.
a measure of thermodynamic activity of gas molecules
a measure of thermodynamic activity of gas molecule s
The fraction of the total static pressure in a gas stream caused by one of the constituents of the mixture.
pressure a gas in a mixture would exert if it was alone in the container. For example, the partial pressure of oxygen in air at 1 atmosphere pressure is 0.2 atm, because oxygen is 20% of the atmosphere.
The pressure that a gas which is a component of a mixture of gases would exert if there were no other gases in the container.
The partial pressure of a gas is the pressure that it would exert if it occupied the container alone.
pressure exerted by a single component of a gas within a gas mixture, or dissolved in a liquid.
The vapor pressure exerted by one component of a gas mixture. In any gas mixture, the total pressure is equal to the sum of the partial pressures that each gas would exert were it alone in the volume occupied by the gas mixture.
The pressure exerted by one gas in a mixture. This is the pressure remaining if all other gases are removed but the volume is unchanged.
Pressure exerted by a single gas within a mixture of gases; is proportional to the relative concentration and total gas pressure.
The pressure exerted by a gas dissolved in plasma or blood in mmHg, for example pO2 is the partial pressure exerted by dissolved oxygen. Partial pressure can be used to tell the amount of that gas dissolved in the blood.
The pressure that a component of a gaseous mixture would have if it alone occupied the same volume at the same temperature as the mixture. See Dalton's law.
in a mixture of gases, each gas has a partial pressure, which is the pressure the gas would have if it occupied that volume alone.
