This table gives data on the variation of the density of some common liquids with pressure and temperature. The pressure dependence is described to first order by the isothermal compressibility coefficient κ defined as
κT = –(1/V) (∂V/∂P)T
where V is the volume and P the pressure, and the temperature dependence by the cubic expansion coefficient α,
αV = (1/V) (∂V/∂T)P
More precise data on the variation of density with temperature over a wide temperature range can be found in Ref. 1. Column definitions for the table are as follows.
Column heading | Definition |
Name | Name of liquid; listed alphabetically by name |
Mol. form. | Molecular formula of liquid |
t | Temperature at which properties are given, in °C |
κT × 104 | Isothermal compressibility coefficient in units MPa-1; value as written is 104 the true value |
αV × 103 | Cubic expansion coefficient, in units °C-1; value as written is 103 the true value |
Name | Synonym | Mol. form. | CAS Reg. No. | t/ºC | κT × 104/MPa-1 | αV × 103/°C-1 |
