Glass Transition
Glass transition refers to the process where certain materials, primarily polymers and some liquids, change from a hard, brittle state to a softer, more flexible state as temperature increases. This transition occurs without a distinct melting point. At lower temperatures, the molecules are tightly packed and less mobile, making the material glass-like. As temperature rises, molecular motion increases, leading to a transition where the material can flow more freely. This phenomenon is important in various fields, including materials science, food science, and pharmaceuticals, as it affects the properties and behaviors of these substances in different conditions.

The glass transition refers to the transformation of a material, typically a polymer or glass, from a hard and brittle state to a softer and more flexible one without melting. This process occurs when the temperature is raised, allowing molecular movements to increase. At this transition, the material behaves more like a rubbery substance, rather than a rigid solid. It's important in various fields, such as food science and materials engineering, as it affects the properties and performance of many materials, influencing everything from the texture of food to the durability of plastics.
