Place your wind charts and isothermal charts for the six days side by side, and study them together.
Most of the tropical animals cannot endure frost, hence the isothermal line of frost is a line across which few tropical animals venture.
Most arctic animals are enfeebled by heat, and the isothermal line which marks off the region in which frost occurs the year round is another great zoogeographical boundary.
Asked as to the isothermal line, Mr. Tyrrell remarked that the isothermal is a line connecting points that have the same mean temperature for the year round.
The main irregularity in the course of the northern boundary of this zone is due to a wedge shaped projection into the zone to the north, due to the well known northern trend of the isothermallines from a point in eastern Saskatchewan.
Within this border-curve, as in the heterogeneous region, the theoretical part of every isothermal must be replaced by a straight line.
Gouy has remarked, to be produced and continued indefinitely, regardless of any difference in temperature; and we seem to witness the incessant motion, in an isothermal medium, of the particles which constitute matter.
Footnote 6: By isothermal diagram is meant the pattern or complex formed when the isothermal lines are arranged in curves of which the pressure is the ordinate and the volume the abscissa.
Young have made known theisothermal diagrams[6] of a certain number of liquid bodies at the ordinary temperature.
Between these two temperatures an isothermalcompression yields a quantity of liquid which increases, then reaches a maximum, diminishes, and disappears.
Footnote 223: On the theory of the isothermal lines, see the papers of Kupfer in Poggend.
As an example of the complete isothermal diagram, there may be given one representing the equilibria in the system composed of water and the reciprocal salt-pair sodium sulphate--potassium chloride for the temperature 0deg (Fig.
We can, however, follow the isothermalfor -20deg, which is the extreme curve on the right in Fig.
From what has been said, and from an examination of the isothermal diagrams, Figs.
The isothermal solubility curves, also, have a similar form.
Lastly, if the temperature lies outside the transition interval, isothermalevaporation of an unsaturated solution of the composition X (Fig.
One more case of isothermal crystallization may be discussed.
The form of the isothermal solubility curves is also of great value for determining whether an inactive substance is a racemic compound or a conglomerate of equal proportions of the optical antipodes.
Such a diagram represents the conditions of equilibrium only for one definite temperature, and corresponds, therefore, to the isothermal diagrams for ternary systems (p.
As this is a point of some importance, it will be well, perhaps, to make it clearer by giving one of the isothermal curves, e.
For tubes of uniform section m is constant; for steady motion W is constant; and for isothermal expansion [tau] is constant.
In other words, the expansion may be regarded as isothermal expansion, the heat generated by friction exactly neutralizing the cooling due to the work done.
The best air compressors give a result about midway between the isothermal and the adiabatic, and the net loss of power directly due to clearance is so small as to be practically unworthy of consideration.
On the contrary, it is a most fallacious system, because it introduces all the disadvantages of water injection without its isothermal influence.
The trade demanded compressors at inaccessible localities, and in many cases it was preferred to sacrifice isothermal results to simplicity of construction and low cost.
The large air head of the initial cylinder is jacketed, also adding to isothermal economy.
We have in the foregoing a remarkable isothermal result.
So much confidence seems to be placed in the isothermal features of this machine that usually no water jacket or spray pump is applied.
The rays emitted from such a body at any temperature must be equal to the full radiation stream in an isothermal enclosure at the same temperature.
Clapeyron gave the general expressions for the latent heat of a vapour, and for the latent heat of isothermal expansion of any substance, in terms of Carnot's function, employing the notation of the calculus.
He determines the value of this function to be J/T by assuming, with Seguin and Mayer, that the work done in the isothermal expansion of a gas is a measure of the heat absorbed.
Carnot obtained the expression for the heat absorbed by a gas in isothermal expansion H = R loge r/F't.
This is the ratio of the adiabatic elasticity of air to the isothermal elasticity.
The ratio of the adiabatic to the isothermal elasticity, required for calculating the velocity of sound, is therefore the same as the ratio of the specific heat at constant pressure to that at constant volume.
The isothermal line of Mackinaw passes in the midst of those countries which alone produce the surplus grain of Europe, viz.
The same isothermal line, passes through Prussia and Poland, the finest grain countries of Europe.
The isothermal line, which passes through Mackinaw, also passes in Wisconsin, nearly as low as 43°, and in the east also deflects south.
Animals, on the contrary, can at pleasure migrate from the equator toward the poles; and this they can more especially doo where the isothermal lines are much inflected, and where hot summers succeed a great degree of winter cold.
