The obtained results are compared with the relevant data for argon. Taking the principle of corresponding states into account, the existence of a region, where the thermodynamic similarity between water and argon takes place, is confirmed. At the same time, there is a region, where the indicated similarity is not observed, and the thermodynamic properties of water demonstrate a peculiar behavior. In particular, an inflection point at a temperature of (91.0 ± 0.2 )<sup>∘</sup>C is observed in the temperature dependence of the curve (∂V/∂T)<sub>P</sub> for water, but not for argon, along the liquid-vapor equilibrium curve. The existence of inflection point in the dependence (∂V/∂T)<sub>P</sub> for water leads to the presence of negative values of (∂V/∂T)<sub>P</sub> at temperatures below 3.98<sup>∘</sup>C, as well as to the intersection of the temperature dependences of isobars (∂V/∂T)<sub>P</sub> in water at a temperature of (42 .0 ± 0 .2 )<sup>∘</sup>C. On the contrary, the temperature dependences of the curves (∂V/∂T)<sub>P</sub> for argon along the liquid-vapor equilibrium curve do not have a corresponding inflection point.</p>}, number={2}, journal={Ukrainian Journal of Physics}, author={Bulavin, L.A. and Rudnikov, Ye.G.}, year={2023}, month={Apr.}, pages={122} }
