In this article, the framework has been prepared to investigate the various thermodynamical properties namely; entropy S, internal energy EINT and Helmholtz free energy FH of some liquid alkali metals using the universal model potential given by Fiolhais et al. with Percus-Yevick hard sphere (PYHS) reference system. The screening influence of six different local field correction functions proposed by Hartree (H), Taylor (T), Ichimaru-Utsumi (IU), Farid et al. (F), Sarkar et al. (S) and Nagy (N) for the first time with universal model potential of Fiolhais et al. are reported. A very good agreement between the presently computed data and experimentally available data is found.
