Answer: Plastics, glass, rubber, metallic glass, polymers, gel, fused silica, pitch tar, thin layer lubricants, and wax are examples of amorphous solids.
Quartz, calcite, sugar, mica, diamonds, snowflakes, rock, calcium fluoride, silicon dioxide, and alum are examples of crystalline solids.
amorphous solid:
The component particles of an amorphous material do not have a regular three-dimensional structure.
Lacking the three-dimensional long-range order of crystalline materials, amorphous solids have a more random arrangement of molecules, exhibit short-range order across a few molecular dimensions, and have physical properties that are significantly different from those of their crystalline counterparts.
Amorphous solids are similar to liquids in that they lack an ordered structure, or a three-dimensional arrangement of atoms or ions. The solid to liquid transformation occurs across a wide temperature range since these substances do not have a sharp melting point. Physical properties of amorphous substances are generally isotropic, meaning that they are unaffected by measurement direction and have the same magnitude in all directions.
What are Crystalline Solids, and what do they do?
Crystalline solids are materials with highly organised arrangements of their particles (atoms, ions, and molecules) in microscopic structures.
A crystal lattice is made up of these organized microscopic structures and accounts for the structure of the solid at any given position. Salt (sodium chloride), diamond, and sodium nitrate are examples of crystalline solids.
