Water is a complex fluid for variety of reasons. Liquid water has a normal liquid-gas critical point and a possibility of a second metastable liquid-liquid critical point close to the freezing transition. The challenge is, therefore, to apply Renormalization Group Theory for fluids, already developed by Professor White in the 1980s, to calculate the thermal properties of water at both near and far from the two critical points. This dissertation will show that using a simple square well potential, the theory gives results that are in good agreement with experimental data for water near and in large adjoining neighborhood of the first liquid-gas critical point.
