Properties of water and its anomalous behaviour

Abstract

Water is a complex liquid that has unusual behaviours, the most famous being the maximum density at 4ºC. Here in this paper it is reported some of its properties. To do so, molecular dynamics simulations were carried out using the water model called TIP4P/2005. The data obtained in those simulations enabled us to study the radial distribution function, the density, the compressibility, the average number of hydrogen bonds and the self-diffusion coefficient of water. It is shown that this model correctly describes the structural, thermodynamic and dynamic properties of water. Furthermore, the anomalous behaviour of the maximum in density among others such as the minimum of the compressibility were also well characterised and in agreement with experimental data
