Abstract : The dynamics and thermodynamics of phase transition in nuclei are studied through experimental results on multifragmentation of systems with masses around 200 nucleons. Nuclear multifragmentation is indeed the phenomenon connected to the liquid-gas phase transition of nuclei. Negative heat capacities and spinodal decomposition are observed in a limited range of available energy, which sign the penetration of the systems in the coexistence zone of the phase diagram and thus a first order phase transition.
