Definition

relative change of pressure with temperature at constant volume:

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

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

variation relative de pression en fonction de la température à volume constant:

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

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