The speed of sound in gaseous cis-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(Z)) has been determined at temperatures between 305 K and 405 K and at pressures up to 1.8 MPa from measurements of the acoustic and microwave resonance frequencies of a small volume (268 cm3) quasi-spherical resonator. Ideal gas heat capacities and acoustic virial coefficients have been directly interpolated from the data. The coefficients of a virial equation of state were obtained from the acoustic data by modelling the intermolecular potential with a hard-core square-well.

Abstract
The speed of sound in gaseous cis-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(Z)) has been determined at temperatures between 305 K and 405 K and at pressures up to 1.8 MPa from measurements of the acoustic and microwave resonance frequencies of a small volume (268 cm3) quasi-spherical resonator. Ideal gas heat capacities and acoustic virial coefficients have been directly interpolated from the data. The coefficients of a virial equation of state were obtained from the acoustic data by modelling the intermolecular potential with a hard-core square-well.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
