Aims

Students will be introduced to problems of equilibrium between phases according to the detail analysis of intermolecular interactions. Consequently, they will be introduced to contemporary principles and procedures applied for numerical prediction of phase equilibrium and phase transitions. Besides theoretical principles, real systems will be discussed with which students could probably meet in praxis.
