In our opinion, specific temperature dependences of the indicated parameters for water are associated with the existence of a network of hydrogen bonds in water under certain conditions. This network is formed by two dynamic structures (the LWD and HDW phases) and is responsible for the hierarchy of anomalous water properties in a wide temperature interval. In addition, it has been shown that the network of hydrogen bonds substantially affects the behavior of the temperature dependence of the sound propagation speed related to the adiabatic coefficient of liquid compressibility. |
