How can anyone differentiate crystalline and amorphous solids?

Open in App

Solution

Difference between crystalline and amorphous solids:
Crystalline solid
Amorphous solid
Crystalline solids do have a regularly ordered structure or a definite characteristic shape.
Amorphous solids do not have any regularly ordered structure or definite characteristic shape.
They have a sharp and characteristic melting point.
They do not have any sharp melting point.
Crystalline solids have a finite and characteristic heat of fusion.
Amorphous solids have no definite heat of fusion as like crystalline solids.
These are Anisotropic in nature since physical properties are different in different directions.
These are mostly of Isotopic nature as they have the same physical properties in all directions.
Crystalline solids are known as true solids.
Amorphous solids are known as pseudo solids.
Example: Sodium chloride, Cesium chloride
Example: Glass, Rubber, Plastic, etc.
