An apparatus containing a T-shaped tube fitted with a rupture diaphragm was developed in order to generate simultaneously two decompression waves traveling in opposite directions through a gas. The speeds of decompression wave fronts observed at ideal gas densities were found to be precisely equal to the calculated values of the speed of sound of equilibrium thermodynamics. Accordingly, the observed speed of the wave front is adopted as the speed of sound at all gas densities. Wave front speeds are determined from transit-times between two piezoelectric transducers mounted face-on to the waves and average speed of the two wave fronts is recorded at the speed of sound at a chosen pressure and temperature. The gas density is determined by discharging the contents of a small side-chamber filled with the gas at this state into a pre-evacuated chamber sufficiently large that the mass of discharged gas is provided with precision by the ideal gas law. The compressibility coefficient is measured at slightly higher pressures and is determined from the isothermal decrease in pressure resulting from a controlled leak of the gas in the T-tube to the small side-chamber. All gas-containing vessels were maintained at constant temperature to within ±0,1°C by immersion in a suitable bath. |
