continuous phase transition

A continuous phase transition occurs when a material changes its state gradually, without sudden jumps, as conditions like temperature or pressure vary. For example, when a metal cools into a superconducting state, its properties change smoothly rather than abruptly. During such transitions, certain characteristics—like density or magnetic properties—change gradually and can often be described using mathematical functions. These transitions are important because they reveal underlying symmetries and universal behaviors in materials, helping scientists understand the fundamental principles governing different states of matter.
