The equation for x and p for this temperature is of the same form 

 as before (see Fig. 3) 



x=17-7p8« 

 One reading was made with the Hgnite at liquid air temperature:

The Adsorption of Carbon Dioxide 



An experiment on the adsorption of carbon dioxide was made 

 with the Hgnite at 20°C. The gas used was that which is manufactured 

 commercially and it was dried by bubbling it through strong sul- 

 phuric acid before it was put into the apparatus. 



The following results show that carbon dioxide is adsorbed much 

 more readily than air:
