Abstract
The data (the speed of sound, the isobaric and isochoric heat capacities, as well as the heat capacity ratio) for liquid neon presented in the NIST Chemistry WebBook are analyzed. It has been shown, based on the representation of the inverse reduced volume fluctuations, that they consist of sufficient discrepancies in the subcritical region. The correction of data in this region of the coexistence curve is evaluated using the fluctuation approach and the theory of thermodynamic similarity.
