Law Of Partial Pressures (Noun)
Meaning
(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.

Examples
- The law of partial pressures, also known as Dalton's law, states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas.
- In a mixture of gases, the pressure exerted by each gas is proportional to its mole fraction, as described by the law of partial pressures.
- According to the law of partial pressures, the partial pressure of a gas in a mixture is directly proportional to its mole fraction in the mixture.
- The law of partial pressures is widely used in chemistry and physics to calculate the pressure of a gas in a mixture, given its mole fraction and the total pressure of the mixture.
- The law of partial pressures was first proposed by John Dalton in the early 19th century, and it has since become a fundamental principle in the study of gases and their behavior.
