1. $\frac{\mathrm{d}\ln \mathrm{G}}{\mathrm{d}{\mathrm{T}}^2}=\frac{∆{\mathrm{H}}_{\mathrm{\upsilon }}}{\mathrm{R}{\mathrm{T}}^2}$
2. $\frac{\mathrm{d}\ln \mathrm{P}}{\mathrm{d}\mathrm{T}}=\frac{-∆{\mathrm{H}}_{\mathrm{\upsilon }}}{\mathrm{R}\mathrm{T}}$
3. $\frac{\mathrm{d}\ln \mathrm{P}}{\mathrm{d}{\mathrm{T}}^2}=\frac{-∆{\mathrm{H}}_{\mathrm{\upsilon }}}{{\mathrm{T}}^2}$
4. $\frac{\mathrm{d}\ln \mathrm{P}}{\mathrm{d}\mathrm{T}}=\frac{∆{\mathrm{H}}_{\mathrm{\upsilon }}}{\mathrm{R}{\mathrm{T}}^2}$
