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 one-eyed man will be King in the country of the blind only if he arrives there in full possession of his partial faculties—that is, providing he is perfectly aware of the precise nature of sight and does not confuse it with second sight ... nor with madness.”
—Angela Carter (1940–1992)
“A tattered copy of Johnson’s large Dictionary was a great delight to me, on account of the specimens of English versifications which I found in the Introduction. I learned them as if they were so many poems. I used to keep this old volume close to my pillow; and I amused myself when I awoke in the morning by reciting its jingling contrasts of iambic and trochaic and dactylic metre, and thinking what a charming occupation it must be to “make up” verses.”
—Lucy Larcom (1824–1893)
“The law before us, my lords, seems to be the effect of that practice of which it is intended likewise to be the cause, and to be dictated by the liquor of which it so effectually promotes the use; for surely it never before was conceived by any man entrusted with the administration of public affairs, to raise taxes by the destruction of the people.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
