Air-Analysis a Practical Treatise on the Examination of Air, With an Appendix on Illuminating Gas (Classic Reprint) (Harlequin Super Romance) - Tapa blanda

Excerpt from Air-Analysis a Practical Treatise on the Examination of Air, With an Appendix on Illuminating Gas

Under average atmospheric pressure, viz., 30 inches Of mercury, a cubic foot Of air weighs about ounces. Under a pressure Of 3 inches Of mercury, a cubic foot Of air weighs about 3 ounce. Under a pressure Of 300 inches of mercury, a cubic foot Of air weighs about I 3 ounces.

In short, the weight Of a given volume Of air or any gas is exactly proportional to the pressure.

Excerpt from Air-Analysis a Practical Treatise on the Examination of Air, With an Appendix on Illuminating Gas

This book is written for the chemist who follows his profession, for the student as a companion in the laboratory, and for the sanitarian.

The charming ease and simplicity and rapidity of much of the work described in its pages will commend it to the chemist, who has hitherto been inclined rather to shun gas-analysis.

The accuracy of modern technical processes of gas-analysis has, we are aware, often been called in question. In particular, it has often been said that measurements over water cannot be accurate because of the solubility of all gases in water. If, in the Hempel apparatus, the large bulk of liquid were boiled out, so as to be devoid of air, there might be reason for the objection. But it is not; and, therefore, the error is restricted to that which arises from the difference of solubility of different gases. It is further to be noted that this error is eluded to a great extent, inasmuch as the contact between the gas and liquids in Hempel's apparatus is too superficial to bring out these differences of solubility.
