No form of the elastic solid theory is admissible except that in which the vibrations are supposed to be perpendicular to the plane of polarization, and the difference between one medium and another to be a difference of density only (Phil.
The density of population is 85.38 per sq.
The accepted atomic weight is accordingly double the density, i.e.
(-268.7° C.), the density of the liquid 0.154, the critical temperature 5° abs., and the critical pressure 2.3 atmospheres (Communications from the Physical Laboratory at Leiden, No.
M., and a population (1901) of 278,119, showing an increase of 49% in the decade and a density of 104 inhabitants to the square mile.
One remarkable discovery, however, of general interest, was the outcome of a long series of delicate weighings and minute experimental care in the determination of the relative density of nitrogen gas - undertaken in order to determine the atomic weight of nitrogen - namely, the discovery of argon, the first of a series of new substances, chemically inert, which occur, some only in excessively minute quantities, as constituents of the 1 The barony was created at George IV.'s coronation in 1821 for the wife of Joseph Holden Strutt, M.P. for Maldon (1790-1826) and Okehampton (1826-1830), who had done great service during the French War as colonel of the Essex militia.
There is no doubt that under average conditions of atmospheric density, the .005 should be replaced by 003, for many independent authorities using different methods have found values very close to this last figure.
The average density increased from 257.21 per sq.
One half of the earth has therefore a greater density than the other.
From this he was led to the final value of 6.566 for the mean density of the earth as compared with that of water (Phil.
The density of solid sulphur is 2 062 to 2'070, and the specific heat 0.1712; it is a bad conductor of electricity and becomes negatively electrified on friction.
A solution of the free acid may be obtained by decomposing the barium salt with dilute sulphuric acid and concentrating the solution in vacuo until it attains a density of about 1.35 (approximately), further concentration leading to its decomposition into sulphur dioxide and sulphuric acid.
The solution obtained may be evaporated in vacuo until it attains a density of 1.46 when, if partially saturated with potassium hydroxide and filtered, it yields crystals of potassium pentathionate, K 2 S 5 0 6.3H 2 0.

The distance between stations on intra-urban railways is governed by the density of local traffic and the speed desired to be maintained.
The density of population in 1900 was 33.5 per sq.
M., and the population in 1905 was 1,684,125, showing a density of 145 inhabitants to the square mile.
There he made the acquaintance of Thomas Andrews, whom he joined in researches on the density of ozone and the action of the electric discharge on oxygen and other gases, and by whom he was introduced to Sir W.
His terminology was vague and provoked caustic criticism from Berzelius; he assumed that all molecules contained two atoms, and consequently the atomic weights deduced from vapour density determinations of sulphur, mercury, arsenic, and phosphorus were quite different from those established by gravimetric and other methods.
It is only by paying great attention to the current density that good results are obtained, since metals other than that sought for may be deposited.
The connexion between the density and chemical composition of solids has not been investigated with the same completeness as in the case of gases and liquids.
Making this substitution, and dividing by d, the density of the substance, we obtain a/d = (N 2 - I)/(N2+2)d.
The actual values of the topic parameters can then readily be expressed in terms of the elements of the crystals (the axial ratios and angles), the density, and the molecular weight (see Groth, Physikalische Krystallographie, or Chemical Crystallography).
Density, specific heat, &c.) of the original and the resulting modification, a change being in general recorded only when polymorphism exists.
Change of temperature usually suffices to determine this, though in certain cases a variation in pressure is necessary; for instance, sodium magnesium uranyl acetate, NaMg(UO 2) 3 (C 2 H 3 O 2) 9.9H 2 O shows no change in density unless the observations are conducted under a considerable pressure.
The strongest and most reliable hold which the ship has upon the whale when moored alongside, is by the flukes or tail; and as from its greater density that part is relatively heavier than any other (excepting the side-fins), its flexibility even in death, causes it to sink low beneath the surface; so that with the hand you cannot get at it from the boat, in order to put the chain round it.
