A simple method to determine the specific volumes of liquids and melts as a function of the temperature. Application to four n-alkanes (C16H34, C18H38, C19H40 and C21H44) under saturating vapour pressure in the 298-573K range

ABSTRACT
A simple method to measure the specific volume of liquids as a function of the temperature is described. In order to validate the method, measurements are carried out in the 298-573 K range on four n-alkanes and the results are compared with previous experimental data from the literature
