A definition of entropy for critical two-phase flows is given. The most probable state of the system is defined. It is shown that a system is in its most probable configuration, if the number of its admissible configurations is maximal. Principal properties of this entropy are examined. The notions for chaotizing factor are formulated. A connection between statistical parameters of the system and parameters of separation curves affinization is validated from this standpoint. One more parameter, mobility factor of a two-phase flow is introduced. Statistical identities for such systems are examined. Entropy connection with governing characteristics of two-phase flows is established.
