Saturation vapor pressure
= Saturation vapor pressure
{title2=$e_s(T)$}
The equilibrium partial <pressure> of a vapour in contact with its condensed phase at a specified <temperature>. With constant specific <latent heat> and negligible condensed-phase volume, $d\ln e_s/dT=L/(R_vT^2)$. The condensed phase and any metastability convention must be specified.
