The process of rapid massive cluster formation at low densities is associated with the process of {ital multifragmentation}. This phenomenon is studied by comparing the free energy for internally formed clusters with the free energy of the homogeneous system. The importance of considering {ital two} freeze-out conditions (entropy-freeze-out and force-freeze-out) in the dynamics leading to multifragmentation is discussed. Calculations of the yield of intermediate mass fragments are made with the expanding-evaporating source model and compared with data. The consequences of distributions in excitation energy, on the observation of multifragmentation, are discussed.
