  It is commonly accepted that strongly interacting matter has several phase
transitions in different domains of temperature and baryon density. In this
contribution I discuss two most popular phase transitions which in principle
can be accessed in nuclear collisions. One of them, the liquid-gas phase
transition, is well established theoretically and studied experimentally in
nuclear multifragmentation reactions at intermediate energies. The other one,
the deconfinement-hadronization phase transition, is at the focus of present
and future experimental studies with relativistic heavy-ion beams at SPS, RHIC
and LHC. Pssible links between these two phase transitions are identified from
the viewpoint of their manifestation in violent nuclear collisions.
