Such solutions are much used in determining the specific gravities of minerals, and in separating them when mechanically mixed as in a pulverized rock.
Physics) Defn: An instrument for determining the specific gravities of liquids, and thence the strength spirituous liquors, saline solutions, etc.
I have taken the specificgravities of the simple minerals from Von Kobell, one of the latest and best authorities, and of the rocks from various authorities.
This experiment may be repeated several times, and is a good illustration of the relative specific gravities of the two gases, and of the importance of the law of universal diffusion already explained at p.

And what are the differing Gravities of the Sea-water, according to the Climats.
By this Statical Instrument we may be assisted to compare the Mercurial Baroscopes of several places (though never so distant) and to make some Estimates of the Gravities of the Air therein.
Prout, from a still more careful investigation of the relative specific gravities of oxygen and hydrogen, showed that if the atom of hydrogen be 1, that of oxygen must be 8.
No person who has attended to the experiments made on the specific gravity of these two gases during the last twelve years, could admit that these specific gravities are to each other as 1 to 14.
I imagine around five gravities or so, if it was to be for some time, especially if one was in a pressure pack.
When loaded with either of the lightest two weights the instrument is specifically lighter than Sikes's hydrometer when unloaded, and it may thus be used for specific gravities as low as that of absolute alcohol.
There are also other balls for showing the specific gravities quite to common water, which make the instrument perfect in its kind.
The marine hydrometers, as supplied by the British government to the royal navy and the merchant marine, are glass instruments with slender stems, and generally serve to indicate specific gravities from 1.
The following table gives the specific gravities corresponding to the principal graduations on Sikes's hydrometer at 60 deg.
Desaguliers himself constructed a hydrometer of the ordinary type for comparing the specific gravities of different kinds of water (Desaguliers's Experimental Philosophy, ii.
He also replaced the letters on the stem by the corresponding specific gravities referred to water as unity.
B represents "a small glass instrument for estimating the specific gravities of liquors," an account of which was promised by Boyle in the following number of the Phil.
Adie's sliding hydrometer is of the ordinary form, but can be adjusted for liquids of widely differing specific gravities by drawing out a sliding tube, thus changing the volume of the hydrometer while its weight remains constant.
The Hydrostatical Balance explain'd, with the Methods of determining the Specifick Gravities of all Sorts of Bodies, whether Solid or Fluid, thereby.
The Praxis of the Hydrostatical Balance, whereby the Specifick Gravities of several particular Bodies are actually found out.
Of the sinking and floating of Bodies immers'd in Fluids; their relative Gravities and Levities; their Situations and Positions.
A TABLE of the Specifick Gravities of several Solid and Fluid Bodies.
Her mind was presently crowded with confused impressions of pleasant men evading her agreeably and making out of her gravities an opportunity for bright sayings, and of women being vaguely solemn and quite indefinite.
Sometimes he worked with disinterested passion and sometimes he was greatly sustained by this thought that here was something that would weave him in with the gravities of her life and give him perhaps a new inlet to intimacy.
The following year he invented an instrument for determining the specific gravities of liquids, which was generally adopted.
Let all elastic fluids be measured by the ounce measure of water, by which the valuation of different cubic inches will be avoided, and the common decimal tables of specific gravities will immediately give the weights of those elastic fluids.
The absolute Gravities of Solids, have a proportion compounded of the proportions of their specificall Gravities, and of their Masses.
Sidenote: Solids whose Masses are in contrary proportion to their Specifick Gravities are equall in absolute Gravity.
It was thus when Cavendish's torsion-balance experiment determined the specific gravity of the earth, and so gave a datum for calculating the specific gravities of the sun and planets.
While these anomalies render untenable the position that the relative specific gravities of the planets are direct indications of nebular condensation; it by no means follows that they negative it.
There are three possible causes of unlike specificgravities in the members of our Solar System:--1.
In considering the specific gravitiesof the heavenly bodies, we have been obliged to speak of the heat evolved by them.
We are shown how it happens that the larger planets have so much lower specific gravities than the smaller, instead of having higher ones, as might have been expected; and we are further shown why Saturn is the lightest of all.
Table of Specific Gravities of Pure Commercial Glycerine with Corresponding Percentage of Water.
An instrument for ascertaining the specific gravities of liquids, and hence their strength, the latter being either in inverse or direct proportion to the former.
Thus interpreted then, the various specific gravities of the planets may be held to furnish further evidences supporting the Nebular Hypothesis.
Referring to the conceivable causes of unlike specific gravities in the members of the solar system, it was said that these might be-- "1.
After days of no-weight, two gravities was punishing.
They had been designed to lift it off of Earth--and they had--against six times the effective gravity here, and with an acceleration of more gravities on top of that.
The moon-rocket had blasted off at six gravitiesacceleration until clear of atmosphere and a little more.
We didn't want to accelerate to any higher gravities than absolutely necessary because of the Gerns on it.
Term used to describe the making uniform of varying specific gravitiesin different cells of the same battery, by adding or removing water or electrolyte.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "gravities" in a variety of sentences. We hope that you will now be able to make sentences using this word.
