Density and Expansivity of Solid Argon


A FULL knowledge of the thermodynamic properties of some simple solid, such as a solidified inert gas, is necessary for the satisfactory development of a rigorous lattice dynamics. When a simple interatomic potential containing two constants is applied to a given substance (see, for example, Barron and Domb1, Henkel2), it is necessary to know at least the density and energy of sublimation at absolute zero so as to determine the constants. In order to verify the theory in detail, it is then necessary to measure three independent quantities such as C p, α and χs, where α is the volume expansivity and x s is the adiabatic compressibility.
