Abstract: A simple model has been used to study the size dependence of cohesive energy, melting temperature and Debye temperature. We have considered W, Ag, Al, Co and Au for the study of size dependence of cohesive energy and Al, Au, Ag, Zn, Bi for size dependence of melting temperature. The results obtained are compared with the available experimental data. A good agreement between theory and experiment encouraged the authors to extend the model to study the size dependence of Debye temperature. The results obtained for the size dependence of the Debye temperature are found to be in good agreement with the experimental data. This supports the validity of the model developed.
