at a fixed temperature andpressure. Exact quantitative experiments have shown thatthe mass of a litre of air at 0° C. and under normal pressure ofthe air at sea level (760 mm. of mercury) is 1.293 grams. 116. Pressure of Air. It is evident that since air has weight it must, like liquids, exert… … Fia. 125.—Globe forweighing air. 102 PRESSURE IN GASES aerial ocean in which we live, is subject to a pressure due tothe weight of the air supported by it.
