what is the difference between amorphous and crystalline solids?
Differences between amorphous and crystalline solids are listed in the given table.
Amorphous solids
Crystalline solids
1
Have irregular shape
1
Have definite characteristic geometrical shape
2
Have only short-range order in the arrangement of constituent particles
2
Have long-range order in the arrangement of constituent particles
3
Gradually soften over a range of temperature
3
Have sharp and characteristic melting point
4
When cut with a sharp-edged tool, they cut into two pieces with irregular shapes
4
When cut with a sharp-edged tool, they split into two pieces with plain and smooth newly generated surfaces.
5
Do not have definite heat of fusion
5
Have definite and characteristic heat of fusion
6
Isotropic in nature
6
Anisotropic in nature
7
Pseudo solids or super-cooled liquids
7
True solids
