The standard paradigm of statistical thermodynamics is explored for five model systems. Three systems belong to the class of lattice models and two to the class of models with hard‐core interaction potentials. The methodology is based on the concept of clusters. It is shown that the study of clusters in the lattice site percolation problem can give us valuable information about the Ising model and also about another Ising‐type spin model which is introduced in the study. In the field of hard‐core systems the concept of clusters is realized in the form of virial expansion and applied to the problem of stability of hard‐sphere mixtures and also to the problem of the existence of a thermodynamic limit for the model of adhesive spheres. © 2000 John Wiley & Sons, Inc.
