Definition

negative relative change of volume with pressure at constant temperature:

κ_{T} = \frac{1}{V} {(\frac{\partial V}{\partial p})}_{T}

where $V$ is volume (ISO 80000-3: Space and time), $p$ is pressure (ISO 80000-4: Mechanics), and $T$ is thermodynamic temperature (thermodynamic temperature)

opposé de la variation relative de volume en fonction de la pression à température constante:

κ_{T} = \frac{1}{V} {(\frac{\partial V}{\partial p})}_{T}

où $V$ est le volume (ISO 80000-3: Space and time), $p$ est la pression (ISO 80000-4: Mechanics) et $T$ est la température thermodynamique (thermodynamic temperature)
