Abstract
Despite intensive research on the structure and molecular dynamics of liquid water is still not known thermodynamic mechanism of differentiation of the extreme points of the temperature dependences of the properties of water. In the present work studied the anomalous temperature dependencies, by using the method of linear approximations. Estimated temperature gradient and the activation energy for each dependency and compared them with the energy of hydrogen bonds and energies of their own and cooperative motions of water molecules in clusters. Found that the reaction rupture of hydrogen bonds limit mainly thermodynamics anomalies dynamic viscosity, self-diffusion and conductivity of water. Thermodynamics cooperative and resonance effects in the cluster structures is the basis of density anomalies, adiabatic heat capacity, speed of sound, surface tension and compressibility. Almost all linear approximation had a fracture in the area of 25 °C. Given the known data suggested that at this point, a phase transition occurs between States of water with varying degrees of helicity of hydrogen bonds.
