Difference between Amorphous and Crystalline solid
Amorphous sollid |
Crystalline Solid |
Amorphous solid are arranged in a irregular pattern. | Crystalline solid are arranges in a regular pattern. |
They undergoes irregular clevage when cut. | They undergoes a clean clevage when cut. |
They are true solid. | They are pseudo solid. |
They are isotropic in nature.
Isotropic since they same physical properties in all direction. |
These are anisotopic in nature.
Anisotropic since they are physical properties are different in different direction. |
They do not have definite heat of fusion. | They have definite heat fusion. |
Amorphous solid have covalently bonded networks. | These crystalline solid have covalent bond, ionic bond, Vander Wall’s bonds and metallic bonds. |
Amorphous solid Are less rigid. | Crystalline solid Are more rigid. |
Amorphous solid have short range order. | They have long range order. |
Amorphous solid has a disordered structure. | Crystalline Solid is Composed of one or more crystals. |
Amorphous solid have a lattice structure. | Crystalline Solid do not Show lattice Structure. |
Amorphous solid Does not produce curved fragments. | Crystalline Solid produce Curved Fragments. |
Amorphous solid has lower molecular mass. | Crystalline Solid has high molecular mass. |
Amorphous solid are not stoichiometric solid. | crystalline solid are stoichiometric solid. |
Amorphous Solid do not have any unit cell. | Crystalline solid has a unit cell. |
All bonds in amorphous solid are not equally strong. | All Bonds in crystalline Solids are equally strong due to their symmetry. |
They have same physical properties in all direction. | They are different physical properties. |
Examples of amorphous solids are : Glass, Polyvinyl chloride etc. | Examples of crystalline solids are : Copper, Sucrose, Sodium Chloride, Potassium nitrate Etc. |
