OXYHYDROGEN See also:

FLAME , the flame attending the See also:combustion of See also:hydrogen and See also:oxygen, and characterized by a very high temperature. Hydrogen See also:gas readily See also:burns in oxygen or See also:air with the formation of See also:water. The quantity of See also:heat evolved, according to See also:Julius See also:Thomsen, is 34,116 calories for each See also:gram of hydrogen burned. This heat-disturbance is quite See also:independent of the mode in which the See also:process is conducted; but the temperature of the flame is dependent on the circumstances under which the process takes See also:place. It obviously attains its maximum in the See also:case of the firing of pure "oxyhydrogen " gas (a mixture of hydrogen with exactly See also:half its See also:volume of oxygen, the quantity it combines with in becoming water, See also:German Knell-gas). It becomes less when the " oxyhydrogen " is mixed with excess of one or the other of the two reacting gases, or an inert gas such as See also:nitrogen, because in any such case the same amount of heat spreads over a larger quantity of See also:matter. Many forms of oxyhydrogen lamps have been invented, but the explosive nature of the gaseous mixture rendered them all more or less in-See also:chief of the second See also:Japanese See also:army See also:corps, which, landing on the Liaotung . See also:Peninsula, carried See also:Port See also:Arthur by See also:storm, and, subsequently See also:crossing to Shantung, captured the fortress of Wei-See also:hai-wei. For these services he received the See also:title of See also:marquess, and, three years later, he became See also:field-See also:marshal. When (1904) his See also:country became embroiled in See also:war with See also:Russia, he was appointed See also:commander-in-chief of the Japanese armies in See also:Manchuria, and in the sequel of See also:Japan's victory the See also:mikado bestowed on him (1907) the See also:rank of See also:prince. He received the See also:British See also:Order of Merit in 1906.
