Air

Oar northerly winds in the beginning of the winter may arise from the weight of the cold northern air overcoming the warmer southern air, which, as the heat lessens, is less loaded with vapours, and therefore more easily gives way to the cold northern and denser air* Hence the frequency of north-west winds at that season* The Complete Weather Guide: A Collection of Practical Observations for Prognosticating the ...

To accomplish this it is evident that the steam must have an elastic force greater than the pressure of the air, _or it could not expand and drive out the waste steam on the other side of the piston, in opposition to the pressure of the air_. " Steam, Steel and Electricity

And air is not an option, because, since the oxygen in air is flammable, air compressed over 1000 psi cannot be stored. Technical FAQ with Lennard Zinn: Blowing up tires, taking them off, and more

This cylinder gives its full volume of air, and apparently a little more at times, because the air is admitted by a concentrated inlet in which free _air is always moving in one direction_. Scientific American Supplement, No. 799, April 25, 1891

"To visitation of the impassive air," is a sonorous verse; but it is not Dante's verse, unless _all detached_ means _on every side is open to visitation_, and _impassive air_ means The Atlantic Monthly, Volume 20, No. 118, August, 1867

Of the 1588 rooms 441 were dark, with no ventilation to the outer air except through other rooms; 635 rooms gave upon twilight “air shafts. V. “Druv into Decency”

After about the year 1790, it was necessary to think of combustions in the air as combinations of a particular gas, or _air_, with the burning substances, or some portions of them. The Story of Alchemy and the Beginnings of Chemistry

The quantity of air taken in with a single inspiration in quiet breathing (_tidal air_) is about 20-30 cubic inches. Voice Production in Singing and Speaking Based on Scientific Principles (Fourth Edition, Revised and Enlarged)

I have computed it, using 1.406 for the ratio of the specific heat of air at constant pressure to that at constant volume, 491. 13° F. as the temperature of melting ice above the zero of the _air_ thermometer, 26,214 feet for the height of a homogeneous atmosphere, and 0.2375 for the specific heat of air, and I find, by means of these constants, 778. Scientific American Supplement, No. 647, May 26, 1888

"Ef you want to know," sez he, "open your winder of a mornin 'et ary season, and you' ll larn thet the best of perfooms is jest fresh air, _fresh air_," sez he, emphysizin ', "athout no mixtur. The Atlantic Monthly, Volume 17, No. 103, May, 1866

The only thing known to make two hydrophobic surfaces adhere in air is Van der Waal's force, so the old question of capillary action has been disproved. Archive 2008-01-01

It appears that they had long contemplated, with philosophical interest, the floating and ascent of clouds in the air, and when they heard of or read Cavendish's theories in regard to _different kinds of air_, it at once struck them that by enclosing some gas lighter than the atmosphere in a bag, a weight might be raised from the earth into the air. Up in the Clouds Balloon Voyages

When a kettle containing liquid air is placed on ice it "boils" because the ice is intensely hot _when compared with the very low temperature of the liquid air_.] The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told

_Air_ into the bigger _hole_ of the _Vessel_, and into the smaller _hole_ of the _Pipe_, we shall clearly find, that there is a greater pressure of the air upon the water in the _Vessel_ or greater _pipe_, then there is upon that in the lesser _pipe_: For since the pressure of the _air_ every way is found to be equal, that is, as much as is able to press up and sustain a _Cylinder_ of _Quicksilver_ of two foot and a half high, or thereabouts; And since of this pressure so many more degrees are required to force the _Air_ into a smaller then into a greater _hole_ that is full of a more congruous fluid.

This was further proved by making the interval in air 0.8 of an inch whilst muriatic acid gas was in the vessel _a_; for on charging the small balls _s_ and S positively, _all_ the discharge took place through the _air_; but on charging them negatively, _all_ the discharge took place through the Experimental Researches in Electricity, Volume 1

When trustees and patrons realize that pure air is absolutely essential to health, and that their children are being slowly poisoned by the foul air of school rooms, then they will construct our halls of learning with a due regard for the laws of hygiene, and students will not droop under their tasks on account of the absence of Nature's most bountiful gift, _pure air_. The People's Common Sense Medical Adviser in Plain English or, Medicine Simplified, 54th ed., One Million, Six Hundred and Fifty Thousand

"It is not true, and it seems to me even absurd to believe that pure air, which has been justly called _vital air_, and which chemists now call _oxygen gas_, can be the radical of saline matters -- namely, can be the principle of acidity, of causticity, or any salinity whatever. Lamarck, the Founder of Evolution His Life and Work
