Definition Of Partial Pressure In Chemistry

partial pressure the component of the total gas pressure accounted for by one gas in a mixture of gases, e.g. in air at 1 standard atmosphere (1 bar, ∼101 kPa, 760 mmHg or torr), 21% is oxygen and the partial pressure of oxygen ( P O 2) is ∼21 kPa or 160 mmHg (torr).Partial pressure ( syn tension) of a gas dissolved in a liquid is defined as the partial pressure of that gas in the gaseous.
