PARTIAL PRESSURE Meaning and
Definition
-
Partial pressure refers to the pressure exerted by a single component in a mixture of gases. In a gaseous mixture, each gas present contributes its own partial pressure, which is a measure of the amount of pressure that gas would exert if it occupied the same volume alone. The total pressure of the mixture is the sum of the partial pressures of all the gases present.
The concept of partial pressure is based on Dalton's Law, which states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of each individual gas. Partial pressure is directly proportional to the mole fraction of that particular gas in the mixture. Therefore, if a gas occupies a larger proportion of the mixture, it will have a higher partial pressure.
Partial pressures are important in various scientific applications, particularly in the field of chemistry and gas laws. They are used to explain gas behavior, determine gas concentrations, and calculate reaction rates. In addition, partial pressures are crucial in the study of gas transport and gas exchange in biological systems like the lungs.
In summary, partial pressure refers to the pressure exerted by an individual gas component in a mixture of gases, contributing to the total pressure. It is a fundamental concept in understanding gas behavior and is widely applied in various scientific fields.

Etymology of PARTIAL PRESSURE
The term "partial pressure" is composed of two words: "partial" and "pressure".
The word "partial" stems from the Latin word "partialis", which means "divided" or "partial". It is derived from the Latin word "pars", meaning "part" or "portion".
The word "pressure" originates from the Latin word "pressura", which means "a pressing or squeezing". It is derived from the Latin verb "premere", which means "to press".
When combined, "partial pressure" refers to the pressure exerted by a single component of a mixture of gases, which is proportional to the fraction of that component in the mixture.
