Abstract
Measurements of the speed of sound in gaseous
cis-1,3,3,3-tetrafluoroprop-1-ene, (R1234ze(Z)), are presented. The
measurements were performed using a quasi-spherical acoustic resonator at
temperatures between 307 K and 420 K and pressures up to 1.8 MPa. Ideal-gas
heat capacities and acoustic virial coefficients over the same temperature
range were directly calculated from the results. The relative accuracy of our
determinations of the speed of sound $w$($p$,$T$) of R1234ze(Z) was
approximately $\pm$ 0.02%. The accuracy of the determination of the ideal gas
heat capacity ratio ${\gamma}^{0}$($T$) was approximately $\pm$ 0.25%. These
data were found to be mostly consistent with the predictions of a fundamental
equation of state of R1234ze(Z).
