as the chlorine isevolved with great rapidity the processgoes on with regularity, and the gas bub-bles up through the solution. The elastic force of the chlorine gas inthe flask is evidently greater than thepressure of the atmosphere; because it balances not only the atmospheric pressure on the… … Fig. 287. 316 CHEMICAL PHYSICS, tube c. The pressure of the atmosphere is measured by H„ theheight of the column of mercury which it supports. We mayalso measure the pressure exerted by the column of liquid a inthe same way ; for when we know its specific gravity, it is easy,by [81], to find the…
