Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1825 edition. Excerpt: ... what degree of dilution the power of inflammation by a strong spark from a Leyden phial was destroyed. I found that for one of the mixture inflammation was prevented by Of Hydrogene, about--8 Oxygene... 9 Nitrous oxide--11 Carburetted hydrogene-1 Sulphuretted Hydrogene-2 defiant gas 1 Muriatic acid gas 2 Silicated fluoric acid gas-Inflammation took place when the mixtures contained of Hydrogene---6 Oxygene... 7 Nitrous oxide---10 Carburetted hydrogene-j Olefiant gas---- Sulphuretted hydrogene-11 Muriatic acid gas--1 Fluoric acid gas---I I hope to be able to repeat these experiments with more precision at no distant time; the results are not sufficiently exact to lay the foundation for any calculations on the relative cooling powers of equal volumes of the gases, but they show sufficiently, if the conclusions of M. M. De La Roche and Berard be correct, that other causes, besides density and capacity for heat, interfere with the phenomena. Thus nitrous oxide, which is nearly one-third denser than oxygene, and which, according to De La Roche and Berard, has a greater capacity for heat in the ratio of 1.3503 to.9765 in volume, has lower powers of preventing explosion; and hydrogene, which is 15 times lighter than oxygene, and which in equal volumes has a smaller capacity of heat, certainly has a higher power of preventing explosion; and defiant gas exceeds all other gaseous substances in a much higher ratio than could have been expected from its density and capacity. The defiant gas I used was recently made, and might have contained some vapour of ether, and the nitrous oxide was mixed with some azote, but these slight causes could not have interfered with the results to any considerable extent. Mr. Leslie, in his elaborate and...
