...refrigerating effect of gaseous hydrocarbons is based upon the characteristically swift evaporation of their solutions. The safety of methyl chloride results from the fact that it does not decompose (i. e. evaporate) when breathed into the blood...
...Extremely versatile, never idle, he learned all that his contemporaries knew about electricity and wrote a history of that mysterious force. By hit-or-miss methods he obtained in his retorts "marine acid air" (hydrochloric acid gas), "vitriolic acid air" (sulphur dioxide), "fluor acid air" (silicon fluoride), "alkaline air" (gaseous ammonia). One day, he tried passing electric sparks through his "alkaline air" and found that it decomposed into nitro gen and hydrogen. Then, "having a notion" that ammonia and hydrochloric acid gas, mixed, might produce a "neutral air," he obtained some of the first pure crystals of sal ammoniac...
...undemonstrative gas, helium, by a process not too costly or laborious to be adopted industrially. By some ingenious discovery he had readily reduced the gas temperature to very nearly absolute zero. The significance: solid helium, crystalline and transparent in glass tubes, would transport far more handily than the gaseous form. Helium gas is so tenuous that it would take comparatively few tubes of the solid to fill a dirigible...
...dust by atmospheric friction. At the moon, it flies on intact, strikes the moon with terrific impact. In a tenth of a second, the meteor is stopped, but it has penetrated two miles into the moon's stony crust. The friction of penetration heats the meteor to gaseous state, under such pressure that there is an instantaneous explosion "500 times as powerful as dynamite." After centuries of bombardment by swarms of meteors, the moon is everywhere pitted as by shell fire, not pocked as by eruptions. Measurements of pits made by meteors that reached the earth unconsumed are alleged...
...physics, beginning with Crookes, have shown that electrically charged rays (alpha, beta or gamma) are deflected by electric or magnetic fields, and produce ionization of gases through which they pass, i.e., electrons are dislocated from their atoms, and the resulting particles, called ions, become carriers of electrical currents. These gaseous ions may also become nuclei for the condensation of water vapor, just as dust particles help to form clouds and precipitate rain. It is, of course, possible that Venus affects terrestrial weather directly by magnetic or electrostatic influences. But it is more likely that it interferes with the solar radiations...
