One of the earliest theories of the liquid state developed by Jäger [1] described an’ ideal liquid’ as a collection of hard spheres of finite diameters comparable to the distances between their centres and held together by cohesive internal pressure. As has been mentioned in Chapter 3, the admission of finite diameters of molecules introduces repulsive interactions and the system of such particles cannot be considered as ideal. In fact, the ideal liquid of Jäger is a slightly imperfect liquid in which repulsive interactions are accounted for in the semi-empirical form of the finite volumes of molecules. Attractive interactions in the form of cohesive internal pressure are introduced irrespective of any molecular model.
