Abstract
In order to determine a volume thermal expansion coefficient of a liquid, a sample of the liquid is placed inside a cell of a calorimeter followed by an incremental increase of pressure inside the cell containing the liquid. After each pressure increase heat flow into the cell and volume of the liquid are measured. Based on results of the measurements of the heat flow and accounting for initially evaluated cell volume, the volume thermal expansion of the liquid is determined.
