Closing in on Jupiter's past 2011-08-03T17:20:16.227Z The idea is to test the effects on the atmospheric window of various pollutants, and also of water vapour, by releasing them into the building. Solar power from space: Beam it down, Scotty 2011-06-23T10:54:47Z Recent research has revealed that this is due to a double chemical action between traces of water vapour and the incandescent metal. The New Gresham Encyclopedia Volume 4, Part 2: Ebert to Estremadura 2011-04-14T02:00:56.200Z But by vaporizing water and weighing the gas so produced, we find that water vapour is nine times heavier than hydrogen: now, 1: 9 = 2: 18, therefore the molecular weight of water gas is 18. Heroes of Science Chemists 2011-12-09T03:00:21.047Z The condenser, by effecting the condensation of water vapour, also brings about the deposition of solid naphthalene, apart from that which naturally condenses owing to reduction of temperature.

Nasa readies jumbo eye in the sky 2010-04-22T19:35:00Z The CO2 emissions are straightforward enough, but plane engines also generate a host of other "outputs", including nitrous oxide, water vapour and soot. Aviation Q&A: the impact of flying on the environment 2010-04-06T11:08:00Z The stratosphere—which extends up to about 55km, where the mesosphere begins—is made even less weather-prone by the absence of water vapour, and thus of the clouds and precipitation to which it leads. 2010-02-01T13:20:00Z As the temperature cooled, and the water vapour became condensed, it entered into chemical combination with the various rocks, producing organic compounds like acetylene, which results from the action of water on calcium carbide. The Mechanism of Life Mention may be made of the part played by water vapour in conditioning many chemical reactions. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 5 "Cat" to "Celt" The high altitude means it is above 99% of the water vapour that absorbs most infrared radiation from space. Nasa readies jumbo eye in the sky 2010-04-22T19:35:00Z Without the sun's heat, we should have no water vapour in the atmosphere; without vapour, no clouds; without clouds, no snow; without snow, no glaciers. The History of the European Fauna The gases are also expelled from the molten metal by lead, carbon dioxide, or water vapour. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 3 "Convention" to "Copyright" They vary much with the condition of the air as to dust, clouds, water vapour, &c. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" Clouds, say the text-books of meteorology, are collections of partly condensed water vapour or of fine ice crystals. Cavalry of the Clouds Hempel pointed out that the efficiency would be increased by inverting this arrangement, since water vapour is lighter than air and consequently rises. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 2 "Demijohn" to "Destructor" Thus the artificial formation of dew and consequent determination of the dew-point is a recognized method of measuring the pressure, and thence the amount of water vapour in the atmosphere. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 3 "Destructors" to "Diameter" Slipher, finds with the spectroscope faint traces of water vapour in the Martian atmosphere. Astronomy of To-day A Popular Introduction in Non-Technical Language Rainfall usually increases with increasing altitude up to a certain point, beyond which, owing to the loss of water vapour, this increase stops. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" Two other passages point to the circulation of water vapour upward from the earth before its descent as rain; one in the prophecy of Jeremiah, the other, almost identical with it, in Psalm cxxxv. The Astronomy of the Bible An Elementary Commentary on the Astronomical References of Holy Scripture Professor Campbell has, however, made similar experiments, and is of opinion that Professor Lowell has been deceived by the water vapour in our own atmosphere. To Mars via The Moon An Astronomical Story There are indications of the existence of an atmosphere around Venus, and the evidence of the spectroscope shows that water vapour is there present. The Story of the Heavens Browne seems to have used only cool water vapour or sometimes water itself. Practical Taxidermy A manual of instruction to the amateur in collecting, preserving, and setting up natural history specimens of all kinds. To which is added a chapter upon the pictorial arrangement of museums. With additional instructions in modelling and artistic taxidermy. Owing to the distance from the chief source of supply of water vapour—the oceans—the air over the larger land areas is naturally drier and dustier than that over the oceans. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" The air was hot and sticky and heavily charged with a shimmering white water vapour. Stubble He thought, however, that if water boiled at such a low temperature, then the proportion of water vapour in the air would be increased, as evaporation would be more rapid than on the earth. To Mars via The Moon An Astronomical Story They seem to indicate that water vapour is a probable constituent in the atmosphere of Mercury, as it is in our own. The Story of the Heavens Of these causes of heating, the discharges in air or water vapour are probably the more important. On Laboratory Arts Against its heights the water vapour of the monsoon is cooled and condensed, so that it falls in the form of rain and feeds the great rivers. From Pole to Pole A Book for Young People The pupils should be led to sum up their observations in some such way as the following: Air often contains much water vapour. Ontario Normal School Manuals: Science of Education The plates of the lunar spectrum show a darkening of the 'a' band, which indicates the presence of water vapour, and we know that is due to the water vapour in our own atmosphere. To Mars via The Moon An Astronomical Story Some of the earlier observers thought that they could distinctly make out some such lines due, as was supposed, to water vapour. The Story of the Heavens It was rapidly discovered after the apparition of the X rays that gases that have become conductors, that is, ionised gases, also facilitate the condensation of supersaturated water vapour. The New Physics and Its Evolution A mist of water vapour above the open leads, condensed by the severe cold. Scott's Last Expedition Volume I For its complete combustion a volume of acetylene needs approximately twelve volumes of air, forming as products of combustion carbon dioxide and water vapour. The Project Gutenberg Encyclopedia Volume 1 of 28 The plates of the spectrum of Mars show a much more definite darkening of the 'a' band, and Professor Lowell contends that this can only be due to water vapour in the atmosphere of Mars. To Mars via The Moon An Astronomical Story We therefore find oxygen, nitrogen, water vapour, and carbon dioxide remaining as permanent components of our air. The Story of the Heavens When acetylene is employed, the yield is pure carbon, for the only by-product is water vapour; but if the carbide process is adopted, the carbon remains mixed with calcium oxide. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power Now, Dr. Stoney finds that in order to retain water vapour permanently a planet must have a mass at least a quarter that of the earth. Is Mars habitable? A critical examination of Professor Percival Lowell's book "Mars and its canals," with an alternative explanation When, however, the air is present in much smaller ratio the combustion is incomplete, and carbon, carbon monoxide, carbon dioxide, hydrogen and water vapour are produced. The Project Gutenberg Encyclopedia Volume 1 of 28 He showed us many slides on the Western Ghats i.e. insectivorous plants, mountain goats, rivers that are formed by condensation of water vapour, plants that flower every ten years, etc. Free from School A double falciform ejection of water vapour from under the kettlelid at both sides simultaneously. Ulysses The object of using this treated carbide is to avoid the effects of the attack of atmospheric humidity or water vapour, which, with ordinary carbide, give rise to the phenomena of after-generation. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power Between calcium carbide and water vapour a double decomposition occurs chemically identical with that between carbide and liquid water; but the physical effect of the reaction and its practical bearings are considerably modified. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The rubber should not be allowed to form a bend hanging down, or water vapour, &c., may condense and extinguish the flame. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The gas accordingly escapes from the cylinder at A still loaded with water vapour, and for a given weight of water introduced much less acetylene is evolved than in the former case.
