Measurements of average energies of hydrogen bonds in water droplets evaporating from a hard surface were analyzed with a mathematical model based on a Gaussian distribution of the number of water molecule clusters with the same energy of hydrogen bonds and the same number of water molecules. The model was derived from results of previous research showing that in bulk water, clusters are formed due to hydrogen bonds, having different numbers of water molecules; as the number of water molecules in the clusters increases, the average energy of the hydrogen bonds also increases; with the evaporation of water droplets, the average energy of hydrogen bonds increases. Thus, in bulk water, at the beginning of evaporation, the maximum number of clusters must have average hydrogen bonds energy of (-E) = 0.1162 eV and contain 12-13 water molecules.
