Dalton's Law of Partial Pressures is a fundamental concept in chemistry that explains the behavior of gases in mixtures. The law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each component gas. Alternative terms for Dalton's Law of Partial Pressures include Dalton's Law, Dalton's Law of Proportions, and Dalton's Law of Combining Volumes. In addition, the concept is sometimes referred to as Dalton's Law of Simultaneous Pressures or Dalton's Law of Multiple Proportions. Regardless of terminology, the law is crucial to understanding the behavior and properties of gas mixtures in a variety of scientific applications, including industrial chemistry and atmospheric science.
