In physics, a change from one state of matter to another. In dynamical systems theory, a change from one mode of behavior to another.
In dynamical systems, a change from one mode of behavior to another, such as from continuous to chaotic behavior.
A large, global change occurs quickly in a system with little or no intermediate forms. Often, the global change occurs through small, local, gradual changes. Example: water goes through a phase transition when heated to steam.
a change from one state (solid or liquid or gas) to another without a change in chemical composition
a sudden shift to a new state, like water becoming ice, or a bull market suddenly heading south
a transition from one phase of a given thing to another, say the transition from water to ice
A change of the state of matter from one phase to another, such as the transition from liquid water to solid ice.
A process by which a systems changes from one state to another state with different properties, as a result of small changes in temperature or pressure.
A movement between static, ordered or chaotic states or back again. Usually used in connection with a change of state in physics from solid, to liquid, to gas or the reverse, but of general applicability in complexity theory.
Transition between two phases of a system e.g. the melting of ice to water is a phase transition. The transition from a crumpled phase to the flat phase of a crystalline membrane is also a type of phase transition.
In thermodynamics, phase transition or phase change is the transformation of a thermodynamic system from one phase to another. The distinguishing characteristic of a phase transition is an abrupt sudden change in one or more physical properties, in particular the heat capacity, with a small change in a thermodynamic variable such as the temperature. In the English vernacular, the phrase is most commonly used to describe transitions between solid, liquid and gaseous states of matter, in rare cases including plasma.
