THE EXPLOSIVE WAVE. 



These compounds satisfy the law fairly closely, with the ex- 

 ception of the carbonic oxide. The isomeric compounds have 

 generally approximate velocities. They enable us to appreciate 

 more exactly the influence of the heat given off, Q, eliminating 

 that of the density, the specific heat of the products, and even 

 of individual composition, which are the same. 



Thus, in order to make a comparison, it is merely necessary 

 to divide the velocities found by V Q! 



Thus 



3-69 



It will be seen in general the coincidence is still more marked, 

 with the exception of the fifth system, in which carbonic oxide, 

 which does not satisfy the general theory, is compared with 

 cyanogen. 



We will now examine the influence of inert gases, which do 

 not participate in the chemical reaction.
