Gibbs-Helmholtz equations

From SklogWiki

Jump to: navigation, search

$H = -T^2 \left. \frac{\partial (G/T)}{\partial T} \right\vert_p$

$U = -T^2 \left. \frac{\partial (A/T)}{\partial T} \right\vert_V$

where

$H$ is the enthalpy
$T$ is the temperature
$G$ is the Gibbs energy function
$U$ is the internal energy,
$V$ is the volume
$A$ is the Helmholtz energy function.
