📚 Quick Study Guide

  • 🧊 Definition: Amorphous solids lack long-range order in their atomic arrangement, unlike crystalline solids. Think of them as disordered structures.
  • 🧱 Isotropy: They exhibit the same properties in all directions, which is known as isotropy.
  • 🔥 Glass Transition Temperature (Tg): Instead of a sharp melting point, they soften gradually over a temperature range.
  • 🔨 Examples: Common examples include glass, rubber, plastic, and gels.
  • 🧪 Formation: Often formed by rapid cooling or preventing crystallization.
  • 📊 Properties: Generally more flexible and less brittle than crystalline solids.
  • 💡 Applications: Used in a wide variety of applications from windows to flexible electronics.
