Alexander Dalton was a Scottish physician and physicist who lived from 1752 to 1828. He is best known for his work on the properties of gases, particularly his discovery of the relationship between the pressure and volume of a gas, known as Dalton's law.
Dalton's law states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of each individual gas. This law is of great importance in chemistry and is used in a variety of applications, such as the design of gas mixtures for anesthesia and the calculation of the partial pressure of gases in the atmosphere.
In addition to his work on gases, Dalton also made significant contributions to the field of meteorology. He was one of the first scientists to study the relationship between weather and atmospheric pressure, and he developed a number of instruments for measuring meteorological variables, such as the barometer and the hygrometer.
