The non-ideality of water/methanol solutions is established by the interplay between hydrophilic and hydrophobic interactions that take place within the system and determine its physical properties. These interactions have a different energetic dependence with the temperature and the measurement of transport parameters, such as self-diffusion coefficient and relaxation time, wich allows one to gain important information about that dependence. Here it is shown how both thermodynamic parameters such as temperature and concentration determine the character and the physical properties of the solutions. Furthermore, the thermodynamic thresholds that separate the different energetic regions are identified.
