“…For liquid argon at 85 ~ measurements of sound absorption [ 19] are consistent with the entire effect being due to shear viscosity and thermal conduction [20], there being no detectable contribution from bulk viscosity. This disagreement may, of course, be due either to the inadequacy of the square well model or to some intrinsic defect in our theory of this model.…”

A simplified kinetic theory is described for spherical molecules interacting according to a square well potential. The statistical premises of this theory correspond closely to those of Longuet-Higgins' and Pople's theory of dense fluids of rigid spheres. The thermal conductivity )~, shear viscosity ~/and bulk viscosity K are predicted to be in the ratiowhere k is Boltzmann's constant and m the mass of a molecule. To calculate any of these coefficients absolutely requires independent information about the equilibrium pair distribution. This may be obtained from the selfdiffusion constant D, whose value is also given by the theory. For argon the measured value of D leads to a theoretical value for ~/ which is in good agreement with experiment; for this liquid however the observed ratio : ~/ is very much smaller than predicted.

“…In such an elastic regime the sound propagation frequency asymptotically reaches a high frequency limit, Ω L = c ∞ Q, where c ∞ > c s is usually referred to as innite frequency sound velocity. This viscoelastic phenomenology allows probing the internal dynamics of the uids by monitoring their eects on sound wave propagation [8,9].…”

“…The values for 90" and 100" were calculated by extrapolation of Hall's expression (15). Hall's theory has been seriously questioned (16, 17) but the expression may be regarded as correct from the empirical standpoint and as such is useful for the extrapolation of data (17). The plot of the excess acoustic absorbance of water us.…”

An examination of the specific volumes of K F and KI solutions over the concentration range 0.1 t o 2.0 171 and over the temperature range 0" to 95' has led to the conclusion that the partial molal expansivity of the salts is due almost entirely to changes in the electrostrictive processes in water with temperature and are not due to changes in the structural effects of the salts on the bulk water with changing temperature. However, structural effects are considered to be of significant magnitude below 70".Un examen des volumes specifiques des solutions de K F et KI dans I'intervalle de concentration d e 0.1 a 2.0 171 et de tempCrature de 0" 95", a permis de conclure que l'expansion partielle molaire des sels est presqu'entierement due aux changements dans les processus Clectrostrictifs de I'eau avec la temperature et non aux changements des effets structuraux des sels sur la masse d'eau. On considere cependant qu'au dessous de 70" des effets de structure peuvent avoir une amplitude significative.[Traduit par le journal]Can.
