Saturation properties and liquid-gas phase transition of nucleus are analysed in the framework of Hatree-Fock theory. We modify Hill-Wheller formula with a finite-size-effect parameter by fitting the zero-temperature properties of nucleus. Employing Gogny effective interaction and phenomenological expression of Coulomb energy, we give the critical temperature of liquid-gas phase transition of nucleus being about 12 MeV, which agrees with the result extracted from heavy-ion collision experiments. It is pointed out that a phenomenological formula of surface energy of hot nucleus is not avaliable in the region where nucleon density is far away from the normal density.
