In the context of the work of British scientist John Dalton, partial pressure refers to the specific pressure that an individual gas would exert if it were the only component occupying the total volume of the mixture at the same temperature.12
According to Daltonās law, the total pressure of a mixture of gases is simply the sum of these individual partial pressures. This principle assumes that the gases behave as ideal gases and do not undergo chemical interactions with one another.12
