The structure of water

Images of water clusters have been reported recently. In this paper, the dynamics of water clusters when dissolving crystals of sodium chloride is studied under a microscope. Images of water clusters have two different colours, a dark outer layer and a shallow inner layer as a water cluster is composed of two phases. Since the experiments were conducted at room temperature there should be no solid phase (ice) in water clusters. Therefore, it is proposed that individual water clusters are composite of two phases, an outer liquid phase and an inner gas phase. Obviously, there will be water clusters everywhere in bulk water and they maintain a certain distance among them; there are spaces among water clusters which are filed with gases and named free volume. At a molecular level, hydrogen atom in a water cluster are pointing outward while oxygen atoms are pointing inward. In this configuration, the cluster is more stable. A formula for calculating the forces inside a water cluster is developed. In this study the structure of water is presented in a new light. The study has opened a door for further understanding of water and its mysterious properties.
