Partial Volume (Amagat's Law of Additive Volume)
The partial volume of a particular gas is the volume which the gas would have if it alone occupied the volume, with unchanged pressure and temperature, and is useful in gas mixtures, e.g. air, to focus on one particular gas component, e.g. oxygen.
It can be approximated both from partial pressure and molar fraction:
-
- Vx is the partial volume of any individual gas component (X)
- Vtot is the total volume in gas mixture
- px is the partial pressure of gas X
- ptot is the total pressure of gas mixture
- nx is the amount of substance of a gas (X)
- ntot is the total amount of substance in gas mixture

Famous quotes containing the words partial, volume and/or law:
“The only coöperation which is commonly possible is exceedingly partial and superficial; and what little true coöperation there is, is as if it were not, being a harmony inaudible to men. If a man has faith, he will coöperate with equal faith everywhere; if he has not faith, he will continue to live like the rest of the world, whatever company he is joined to.”
—Henry David Thoreau (1817–1862)
“To be thoroughly conversant with a Man’s heart, is to take our final lesson in the iron-clasped volume of despair.”
—Edgar Allan Poe (1809–1845)
“Our law very often reminds one of those outskirts of cities where you cannot for a long time tell how the streets come to wind about in so capricious and serpent-like a manner. At last it strikes you that they grew up, house by house, on the devious tracks of the old green lanes; and if you follow on to the existing fields, you may often find the change half complete.”
—Walter Bagehot (1826–1877)
