WebFeb 27, 2024 · Actually, the experimentally observed glass transition is not even a true phase transition. It is a kinetic crossover, admittedly quite sharp, through which a liquid that, upon cooling, has become too viscous to flow and relax in a reasonable observation time (by anthropic standards) falls out of equilibrium. WebA liquid transforms to a glass is simple transformation and not a phase transition. Chemically glass is indeed super-cooled liquid. It is liquid of extremely high viscosity, that is the...
