Question

Give one example of amorphous substance.

Answer 1

• Amorphous, or non-crystalline, solids lack this long-range order. Accordingly, they lack the elasticity, distinct melting points, and other properties of crystalline solids.
• Amorphous solids lack a characteristic geometry, have identical properties along all axes, have wide ranges over which they melt, and break to form curved or irregular shapes.
  
• Example of an amorphous solid is glass. However, amorphous solids are common to all subsets of solids. Additional examples include thin film lubricants, metallic glasses, polymers, and gels.
