Conclusions

  1. 1.

    The molecular velocity of sound does not remain constant in response to changes produced by pressure.

     
  2. 2.

    Rao's rule cannot be used to deduce the degree n to which the volume is raised in the repulsion law; instead, the velocity of sound as a function of pressure should be used. Then n is found as being close to 3 for many organic liquids.

     
  3. 3.

    Allowance should be made for the finite velocity of sound within the molecules. The velocity in the free gaps is dependent on the interaction between the particles and has a negative temperature coefficient.

     
  4. 4.

    The velocity of sound in a liquid is dependent on the degree of order of the molecules.
