3. Mixtures. 



For five mixtures the pressui-e at the end of the condensation 

 was measured at three different temperatures. Not more than \ "'„ 

 of the gas was uncondensed. 



The composition of the mixtures was given above. 



The results are contained in Table 6: 



When Jog. p was drawn as a function of — for argon, nitrogen 



and the mixtures, a set of straight lines was obtained which converge 

 at higher temperatures. The values of p and T which will be used 

 later on for the construction of the px- and 7',c-diagrams were taken 

 from this graphic representation.
