Comparing a single molecule of aqueous vapour with an atom of either of the main constituents of our atmosphere, I am not prepared to say how many thousand times the action of the former exceeds that of the latter.
Aqueous Vapour in relation to the Terrestrial Temperatures.
Water is, to some extent, a volatile body, and our atmosphere, resting as it does upon the surface of the ocean, receives from it a continual supply of aqueous vapour.
Eitner has also shown, by direct investigation on mixtures of other combustible gases and air, that the range of explosibility is greatly reduced by increase in the proportion of aqueous vapour present.
Aqueous vapour, in the form of fog or mist, as is well known, gives to our sensation a feeling of cold, and interferes with the healthy action of the skin and the lungs; the cause being its property of absorbing heat from our person.
By reason of these properties, aqueous vapour acts as a kind of blanket upon the ground, and maintains upon it a higher temperature than it would otherwise have.
Tyndall, is simply due to the difference in the quantity of aqueous vapour present in the atmosphere.
This may be expressed thus: the maximum tension of aqueous vapour (and of all other vapours) saturating a space in a vacuum or in any gas is the same.
The maximum pressure for all temperatures may be found in the tables made from observations on the pressure of aqueous vapour.
The quantity f will be equal to this maximum pressure of aqueous vapour.
At this time I was brooding over experiments on the absorption of radiant heat by aqueous vapour.
Now there are various liquids whose weight is not greater than that of water, while the weight of their vapours, bulk for bulk, is five or six times that of aqueous vapour.
In fact, aqueous vapour is without a parallel in these particulars; it is not only the lightest of all vapours, in the common acceptation of that term, but the lightest of all gases except hydrogen and ammonia.
Janssen on the absorption-bands of aqueous vapour.
But what, then, will be the effect of introducing a quantity of aqueous vapour into an atmosphere this nature?
In the given circumstances, then, aqueous vapour would be forced by these conditions to give up a very large portion of its energy to the other atmospheric constituents.
It will be readily seen, however, that under the same conditions the energy state of aqueous vapour differs very considerably from either, for by the same method as before the energy per pound of aqueous vapour is equal to {(511 x 0.
The products consist at first in aqueous vapour, then a very inflammable volatile oil, which causes boiling oil to take fire spontaneously; and next carburetted hydrogen gas, with carbonic acid gas.
These indicate a deficiency of aqueous vapour, and an excess of nitrous acid.
These are Oxygen, Carbonic-acid gas, Aqueous vapour, Nitrogen, and Ammonia.
Magnus considered that the remarkable effect of aqueous vapour observed by Tyndall might have been caused by condensation on the polished internal walls of his experimental tube, or on the rocksalt plates at either end.
Tyndall's experiment on the great diathermancy of dry air agreed much better with meteorological phenomena, but he appears to have exaggerated the effect of aqueous vapour.
Radiation is observed to take place freely through the atmosphere at times when the proportion of aqueous vapour is such as would practically stop all radiation if Tyndall's results were correct.
The atmosphere at a given temperature is capable of retaining only a given quantity of aqueous vapour, invisibly diffused through it, at which temperature it is said to be saturated.
In our climate the air is never completely dry, nor completely saturated with moisture, and the amount of aqueous vapourheld in suspension is very variable.
The phenomena depending on the presence ofaqueous vapour in the atmosphere which especially under the notice of the astronomer are Refraction, Twilight, and the Twinkling of the Stars.
The fact that the Earth is surrounded by a considerable atmosphere largely composed of aqueous vapourhas a material bearing on the success or failure of observations made on the Earth of bodies situated at a distance.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "aqueous vapour" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
