the atmosphere on i sq. in.is .49 X 30 = 14.7 Ib. That is, the at-mosphere exerts a pressure of 14.7 Ib.(nearly 15 Ib.) per square inch, on every-thing on the earths surface. Pressure of the atmosphere per squarecentimeter. — To calculate the pressureof the atmosphere on each square centi-meter, we… … FIG. 38. — Measuring at-mospheric pressure. MECHANICS. GASES 55 i cu. cm. of mercury weighs 13.6 g. Therefore the pressureof the atmosphere on i sq. cm. is 13.6 X 76 = 1033.6 g. LAWS OF NATURE WHICH APPLY TO GASES Gases have weight and exert pressure. — We have foundthat air has weight; that, like…
