Definition of Law of partial pressures

1. Noun. (chemistry and physics) law stating that the pressure exerted by a mixture of gases equals the sum of the partial pressures of the gases in the mixture; the pressure of a gas in a mixture equals the pressure it would exert if it occupied the same volume alone at the same temperature.

Medical Definition of Law of partial pressures

1. Each gas in a mixture of gases exerts a pressure proportionate to the percentage of the gas and independent of the presence of the other gases present. Synonym: law of partial pressures. (05 Mar 2000)
