Resumen:
Abstract. In this communication we analyze the behavior of excited drops that undergo fragmentation. Wefocus our attention on two scenarios: in the rst one the system is free to expand, while in the second oneit is con ned inside a spherical volume. It is shown that the Caloric Curve of free expanding systems doesnot display a vapor branch. In the case of constrained ones, they behave as undergoing a rst order phasetransition at low densities while as a second order one at high densities. The transition from liquid-like tovapor-like behavior is signaled both by the caloric curves and thermal response functions.
