Liquid alkali metals: Equation of state and reduced-pressure, bulk-modulus, sound-velocity, and specific-heat functions

In this paper we extend our previous work on universality in solids to the study of liquid metals. As in the case of solids, to a good approximation, in the absence of phase transitions, plots of the logarithm of the reduced-pressure function H, of the reduced-isothermal-bulk-modulus function b, and of the reduced-sound-velocity function v are all linear in 1-X. Finally, we demonstrate that ln($C_p$/$C_V$) is also linear in 1-X, where X=(V/$V_0$ ${)}^{1/3}$, and $V_0$ is the volume at zero pressure.
