kinetic glass transition
The kinetic glass transition is the process where a liquid gradually becomes a glass as it cools without crystallizing. Unlike melting, where solids turn directly into liquids, cooling a liquid slowly decreases its molecular movement until it becomes so thick that it behaves like a solid, but without an ordered crystal structure. This transition depends on how fast the material cools; if cooled quickly, it forms a glass because molecules don't have time to organize. The kinetic aspect emphasizes that the change is driven by the rates of molecular motion slowing down, rather than a sharp thermodynamic phase change.
