TABLE 86. Relative Gas Volumes at Various Pressures. 



The following table, deduced by Mr. C. Cochrane, from the PV curves of Amagat and other 

 observers, gives the relative volumes occupied by various gases when the pressure is reduced from 

 the value given at the head of the column to i atmosphere: 



* Carbon dioxide is liquid at pressures greater than 90 atmospheres.
