Wikipedia - Phase Transition
Field of reference: Physics
Description: Second-order phase transitions are common phenomena in e.g. condensed matter physics, particle physics, early-universe physics, etc. By its very definition, a "phase" refers to the global state of a system, or a sub-system, but obviously not to individual particles. In second order phase transition, as one gets closer to the phase-transition point sub-systems begin to feel larger and larger portions of the systems and align themselves with the part of the system that they are correlated with in such a manner that the entropy is maximized and the energy is minimized. The "correlation length" becomes infinite at the transition point, i.e. each sub-system "feels" the rest of the system in its entirety.
