Abstract
A dependence of the van der Waals volume parameter on temperature in cubic equations of state is analysed from the point of view of a consistency in the description of the compressed liquid region. The analysis shows that there may be a region in a PϱT space where the thermal pressure coefficient and the isobaric thermal expansion coefficient are negative if the van der Waals volume parameter decreases with increasing temperature. The results of the analysis are illustrated with a volume-translation method, which is the special case of the temperature dependence of the van der Waals volume parameter.
