Table 1 23. 

 ABSORPTION OF CASES BY LIQUIDS.* 



141 



* This table contains the volumes of different gases, supposed measured at 0° C. and 76 centimetres' pressure, which 

 unit volume of the liquid named will absorb at atmospheric pressure and the temperature stated in the first column. 

 The numbers tabulated are commonly called the absorption coefficients for the gases in water, or in alcohol, at the 

 temperature t and under one atmosphere of pressure. The table has been compiled from data published by Bohr & 

 Bock, Bunsen, Carius, Dittmar, Hamberg, Henrick, Pagliano & Emo, Raoult, Schonfeld, Setschenow, and Winkler. 

 The numbers are in many cases averages from several of these authorities. 



Note. — The effect of increase of pressure is generally to increase the absorption coefficient. The following is 

 approximately the magnitude of the effect in the case of ammonia in alcohol at a temperature of 23° C. : 



iP = 45 cms. 50 cms. 55 cms. 60 cms. 65 cms. 

 o.a=:69 74 79 84 88 



According to Setschenow the effect of varying the pressure from 45 to 85 centimetres in the case of carbonic acid in 

 water is very small.
