摘要：

Measurement of resonant frequencies of acoustic standing waves In gases confined to a spherical cavity leads to accurate sonic speeds. These In turn are related thermodynamically to the ideal gas reference state heat capacities and the second acoustic virial coefficients of the sample gases. The experimental procedure Is described and results are given for n -butane and isobutane. A technique that uses argon as a buffer gas allows the procedure to be extended to include studies on vapors of volatile liquids. Results on n -heptane are presented. © 1990, American Chemical Society. All rights reserved.
