Dalton's Law of Partial Pressures

Dalton's Law of Partial Pressures states that in a mixture of gases, each gas exerts its own pressure independently, as if it alone occupied the entire container. The total pressure of the mixture is the sum of all these individual pressures. This means that the pressure contributed by each gas depends on its amount and nature, regardless of the other gases present. The law helps predict how gases behave together, such as in the atmosphere or in chemical reactions, by understanding that each component’s pressure adds up to the total pressure we measure.
