Abstract
The effect of gravity on measurements of the sound velocity and specific heat near the gas-liquid critical point is calculated in detail, using the "linear model" parametric equation of state. It is found that the linear model is consistent with the best available experimental data, both in gravity-free and gravity-dominated regions, with a choice of the exponent equal to 0.06 ± 0.02.
