Mention on what basis are crystalline solids different from amorphous solids.
Understanding the differences between crystalline and amorphous solid:
Crystalline Solid | Amorphous solid |
Crystalline solids are formed when the constituent particles are arranged in a perfect order. | The constituent particles of amorphous solid are irregularly arranged. |
Crystalline solids have a sharp melting point. | Amorphous solids have verying melting point and it has a range. |
Crystalline solids give sharp edges upon cutting. | Amorphous solids give rough edges upon cutting. |
Crystalline solids show anisotropic behaviour. | Amorphous solids show isotropic behaviour. |
Crystalline solids are rigid and have a definite shape. | Amorphous solids do not have a definite shape. |
Crystalline solids do not have the tendency to flow. | Amorphous solids are super cooled liquids because of their tendency to flow, |
Example: Sodium Crystal, Quartz, | Example: Quartz Glass, PVC, |
