| 单词 | perfect gas |
| 例句 | Thomson's scale enables a perfect gas to be defined, and the deviations of the properties of ordinary gases from those of such a gas to be observed and measured. Lord Kelvin An account of his scientific life and work 2012-04-06T02:00:32.097Z The usual manner of testing the expansion curve of a diagram is to compare it with a curve representing Mariotte’s law for the expansion of a perfect gas. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z Contracting, according to Lane's law, its temperature must rise until its density becomes such that it no longer behaves as a perfect gas. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z They are the cases of mixtures of perfect gases, and of very dilute solutions. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 3 "Electrostatics" to "Engis" 2011-02-06T03:00:53.093Z Instead of behaving like a perfect gas, in which every quark goes its own way independent of the others, the plasma seemed to act like a liquid. 2010-02-15T22:23:00Z In an elastic wave propagated from a centre of impulse in an infinitely extended volume of a perfect gas, normal vibrations are alone propagated—as is the case with sound in air. The Eruption of Vesuvius in 1872 The relation between the temperature, pressure, and weight of steam is not quite proportional to the volume, because steam is not a perfect gas, and does not, therefore, strictly follow Mariotte’s law. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The air thermometer agrees most nearly with that of the ideally perfect gas thermometer, while the mercurial thermometer differs very much from it in some cases. Scientific American Supplement, No. 647, May 26, 1888 Part of the experimental knowledge required for this purpose is the values of the gas-constants, which prove to be the same for all nearly perfect gases. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 3 "Electrostatics" to "Engis" 2011-02-06T03:00:53.093Z Their density must be very low, and their state that of a perfect gas. The New Heavens Lastly, the pressure itself will vary proportionally with the absolute temperature, as defined by the theory of a perfect gas, and will serve to determine it. Scientific American Supplement, No. 441, June 14, 1884. But steam is not a perfect gas, as is evidenced by the fact that its volume does not increase in a ratio inverse to its pressure. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z Ultimately, it was found that the quantities of heat required to raise equal masses of the more perfect gases, through equal ranges of temperature, were inversely proportional to their combining weights. The Advance of Science in the Last Half-Century This expansion, nevertheless, causes a fall in the temperature, because the gas in the experiment is not a perfect gas, and, by an ingenious process, the refrigerations produced are made cumulative. The New Physics and Its Evolution The process of shrinkage and rise of temperature goes on so long as they remain in the state of a perfect gas. The New Heavens The woman had been set free -- volatilized like Clerk Maxwell's perfect gas; almost brought to the point of explosion, like steam. The Education of Henry Adams When a perfect gas dilates in a vacuum its entropy increases, and yet the temperature does not change, and the gas has neither been able to give nor receive heat. The New Physics and Its Evolution The analogy with a perfect gas naturally becomes much greater as the solution becomes more diluted. The New Physics and Its Evolution It is in the fluid state, and perhaps in conditions opposed to those of a body in the state of a perfect gas. The New Physics and Its Evolution Osmosis applied to Solution: Van t'Hoff's discoveries—Analogy between dissolved body and perfect gas—Faults in analogy. The New Physics and Its Evolution One could not stop, even to enjoy the charms of a perfect gas colliding seventeen million times in a second, much like an automobile in Paris.
