An acoustic Greenspan viscometer was used to measure the kinematic viscosity and speed of sound in the gases: CO, CO2, SiF4, SF6, C4F8, and NH3. The measurements cover the temperature range 220 K to 375 K, and pressures up to 3.4 MPa or 80% of the sa

We determined the zero-density viscosity and thermal conductivity of argon with a standard uncertainty of 0.084% in the temperature range 200 K to 400 K. This uncertainty is dominated by the uncertainty of helium's viscosity , which we estimate to be

The viscosity of seven gases (Ar, CH4, C3H8, N2, SF6, CF4, C2F6) was determined by interpreting frequency-response data from a Greenspan acoustic viscometer with a detailed model developed by Gillis, Mehl, and Moldover. The model contains a parameter

The speed of sound was measured in gaseous nitrous oxide (N2O) and nitric oxide (NO) using an acoustic resonance technique with a relative standard uncertainty of less than 0.01%. The measurements span the temperature range 200 to 460 K at pressures

The speed of sound was measured in gaseous chlorine using a highly precise acoustic resonance technique. The data span the temperature range 260 to 440 K and the pressure range 100 kPa to the lesser of 1500 kPa or 80% of the sample's vapor pressure.

Recent quantum mechanical calculations of the interaction energy of pairs of helium atoms are accurate and some include reliable estimates of their uncertainty. We combined these ab initio results with earlier published results to obtain a helium-hel

We present new vapor phase speed-of-sound data u(P, T), new Burnett density–pressure–temperature data ρ(P, T), and a few vapor pressure measurements for sulfur hexafluoride (SF6). The speed-of-sound data spanned the temperature range 230 K≤T

A cylindrical resonator was employed to measure the sound speeds in gaseous CF4 and C2F6. The CF4 measurements span the temperature range 300 to 475 K, while the C2F6 measurements range from 210 to 475 K. For both gases, the pressure range was 0.1 MP
