Phase diagrams calculated using the literature data for water isotopologues and noble substances have been presented. The principle of corresponding states when caloric variables are applied was verified. It was shown that in the reduced temperature, pressure, and chemical potential coordinates, the water isotopologues form a group of substances and have similar phase diagrams. On the other hand, inert substances, starting from argon, form another group with similar phase diagrams in the same coordinates. At the same time, helium and neon, for which the de Boer quantum parameter is substantial, have phase diagrams different from those for other noble substances. Phase diagrams of tritiated water, T2O, and radon, Rn, have been predicted.
