The speed of sound u in carbon dioxide has been measured along seven isotherms at ลฝ . temperatures between 220 and 450 K by means of a spherical resonator. At supercritical temperatures, the greatest pressure on each isotherm was chosen to correspond to approximately one-half of the critical density
The speed of sound has been measured in nitrogen on four isotherms at TrK s 250, 275, 300, and 350, and at pressures between 0.1 MPa and 30 MPa. The measurements were made using a spherical resonator operating at frequencies between 5 kHz and 26 kHz where the speed of sound in nitrogen differs signi
The speed of sound u in gaseous argon has been measured along 21 isotherms at temperatures T between 110 K and 450 K. At Te150 K, the greatest pressure on each isotherm was the lesser of 19 MPa and the pressure at which the estimated density was half its critical value. Below T=150 K, the greatest p
The speed of sound in gaseous propane has been measured along seven isotherms in the temperature range 225 K to 375 K at pressures up to the lower of 0.85 MPa and 80 per cent of the vapour pressure. The results have a precision of 0.001 per cent or better and an overall uncertainty, including an all
