ley de las presiones parciales de Dalton
- According to Dalton's law of partial pressures, the total pressure in a mixture of gases equals the sum of the pressures each gas would exert if it were alone.
Examples
-
When mixing oxygen and nitrogen, Dalton's law of partial pressures helps predict the resulting pressure.
-
According to Dalton's law of partial pressures, the total pressure in the vessel was the sum of all the gases present.
-
Chemists often rely on Dalton's law of partial pressures when analyzing the behavior of gas mixtures.
-
Dalton's law of partial pressures is fundamental in chemistry.
-
According to Dalton's law of partial pressures, gases behave independently.
-
Chemists often use Dalton's law of partial pressures to accurately calculate the total pressure in gas mixtures.
-
When analyzing a gas mixture, scientists apply Dalton's law of partial pressures to determine the contribution of each individual gas to the total pressure.
Synonyms
In a gas mixture, total pressure equals the sum of pressures each gas would make alone
Total pressure of a gas mixture equals the sum of the pressures of each gas

Morphology
Dalton's + law + of + partial + pressure
The phrase is largely compositional: 'law' + 'of partial pressures' straightforwardly signals a scientific rule concerning 'partial' pressures, and 'Dalton's' marks it as a named law. However, the precise quantitative content (that total pressure equals the sum of individual partial pressures) is specialized, technical knowledge not predictable from the words alone, so a learner would grasp the general topic but not the full meaning without prior exposure.
Etymology
Dalton's law of partial pressures comes from Dalton's idea that each gas in a mix pushes on the container as if it were alone. Imagine each gas making its own small 'push', its partial pressure, and these 'pushes' add up, so the total pressure is the sum of all the parts.
