The following table gives the values of 7 for some other gases, which are 

 of interest : 



VALUES OF 7. 



Values of n.

266. When we know the value of 7, it is obviously possible to calculate 

 the value of n from the formula 



2 



7 = 1 + 



71 + 3* 



This has been done in the following table of values of (w + 3). The 

 values of (w + 3) obtained from C p and C v separately (pp. 218, 219) are given 

 for the sake of comparison.
