We report on a new determination of k using acoustic thermometry of helium-4 gas in a 3-litre quasi-sphere. The method is similar to that used in our own experiments on helium and argon with a 0.5-litre resonator. We find for the universal gas constant R = 8.3144597 (49) J·mol-1·K-1. Se hela listan på engineeringtoolbox.com Helium is the least water-soluble monatomic gas, and one of the least water-soluble of any gas (CF 4, SF 6, and C 4 F 8 have lower mole fraction solubilities: 0.3802, 0.4394, and 0.2372 x 2 /10 −5, respectively, versus helium's 0.70797 x 2 /10 −5), and helium's index of refraction is closer to unity than that of any other gas.
