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

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
