(chemistry) law stating that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation

(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

(chemistry) law stating that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation

though the volume of a gas absorbed by a liquid remains constant, the weight of the absorbed gas rises and falls in proportion to the pressure.

The 1. that the tension of a mixture of several gases or of a gas and a vapor is equal to the sum of the tensions which each would separately possess.

A principle determining that the tension and the amount of the vapor which will saturate a given space at a given temperature are the same whether the space is completely empty or filled with a gas.

See 1. of multiple proportions, under law.
