The determination of the gas constant from the speed of sound
Abstract
The determination of the gas constant from the speed of sound in argon at 273.16 K requires an estimate of the corrections due to the imperfection of the gas. These corrections are calculated both from measured values of the second virial coefficient and from the Ar-Ar intermolecular potential. The results suggest that the recent measurements of the speed of sound by Quinn, Colclough, and Chandler (1976) lead to a gas constant of (8.3148 + or - 0.0003) J /K per mol, which is a little above the presently accepted value but not outside the sum of the estimated errors of the two results.
