In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
The Post Secondary Transition For High School Students with Disabilities refers to the ordinance that every public school district in the United States must provide all students with disabilities ages 3 through 21 with an individualized and free appropriate public education in the least restrictive environment.
The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. [2]
Secondary education is the last six or seven years of statutory formal education in the United States. It culminates with twelfth grade (age 17–18). Whether it begins with sixth grade (age 11–12) or seventh grade (age 12–13) varies by state and sometimes by school district. [1] Secondary education in the United States occurs in
A bypass transition is a laminar–turbulent transition in a fluid flow over a surface. It occurs when a laminar boundary layer transitions to a turbulent one through some secondary instability mode, bypassing some of the pre-transitional events that typically occur in a natural laminar–turbulent transition.

A primary kinetic isotope effect (PKIE) may be found when a bond to the isotopically labeled atom is being formed or broken. [3] [4]: 427 Depending on the way a KIE is probed (parallel measurement of rates vs. intermolecular competition vs. intramolecular competition), the observation of a PKIE is indicative of breaking/forming a bond to the isotope at the rate-limiting step, or subsequent ...
Normative school transitions refer to the transitions of students from elementary school to middle school and from middle school to high school. As each transition occurs, the student generally undergoes many different changes. These changes can be anything from an increase in the size of the school, to the change in friends that one meets.
A Mott transition is a metal-insulator transition in condensed matter. Due to electric field screening the potential energy becomes much more sharply (exponentially) peaked around the equilibrium position of the atom and electrons become localized and can no longer conduct a current.
