law of partial pressures

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
Hypernyms: ↑law, ↑law of nature

: a statement in physics: the component of the total pressure contributed by each ingredient in a mixture of gases or vapors is equal to the pressure that it would exert if alone in the same enclosure — called also Dalton's law
