Equations of state for helium, hydrogen, deuterium, nitrogen, oxygen, carbon monoxide, carbon dioxide, and methane at high temperatures and pressures

Equations of state are constructed for $\mathrm{He}$, $\mathrm{Ar}$, $\mathrm{H}_2$ , $\mathrm{D}_2$ , $\mathrm{N}_2$, $\mathrm{O}_2$, $\mathrm{CO}$, $\mathrm{CO}_2$, and $\mathrm{CH}_4$ in the temperature range of $(1-20)\times10^3$ K and at pressures up to $40$ GPa on the basis of the model of canonical equation of state previously proposed by us.
