For both historical and practical reasons, the thermodynamical properties of water have been extensively studied, and much is known about their peculiarities. A number of recalcitrant open questions remain, however. The so-called anomalous expansion of water referred to above, is still the subject of active research. In this and many other similar problems, simplified lattice models of reduced dimensionality can be useful
Out aim in this work is to generate the simplest possible lattice model that qualitatively captures the short-range interaction between water molecules, obtain its partition function analytically, and derive its thermodynamical properties. We show that even this toy model will, without any fine-tuning, produce distinct states/quasi-phases
