✦ Synopsis
Using the available thermodynamic data on liquid hydrogen, deuterium, and neon, and in addition our own measurements of the sound velocity in saturated liquid deuterium and neon, the density, sound velocity, and isentropic compressibility for saturated liquid Ne-nH2 and Ne-nD2 mixtures are calculated by assuming idea/mixtures.
To check this assumption, density and sound velocity are measured in some mixtures. The idea/ mixture model is qualitatively fulfilled. Densities are slightly lower and compressibilities moderately higher than they should be in the idea/case.
The most striking result is that mixtures with intermediate neon content (50-90 mole% neon) have very low sound velocities: at 31 K in Ne-H2 as low as 250 m/s. This is due to the extraordinary differences in density and compressibility of the constituents. Ne-H= and Ne-D~ mixtures behave in a similar way, but the effect is less pronounced in deuterium mixtures.
