The Two-Structure Model and the Heat Capacity of Water
According to current theories, the structure of liquid water can be described in the following manner. When ice melts, some of the water molecules enter the interstices of the ice lattice, this being responsible for the decrease in volume on melting. The molecules that do not enter the interstices form an ice-like lattice, which is in thermodynamic equilibrium with the molecules moving in the interstices. In general outline, these are the present concepts of the structure of liquid water on which the two-structure model is based.
