The globe is first weighedempty, and then full of air,… … Fig. 307, 3o8 On Heat. [335- air and gas. The quotient, obtained by dividing the latter by the former,gives the specific gravity of the gas. It is difficult to make these determina-tions at the same temperature and pressure, and therefore all the weightsare reduced to zero and the normal pressure…
