Solution
| Points | Crystalline solids | Amorphous solids |
| Arrangement | The constituents particles are arranged in regular order. | The constituents particles show disordered arrangement. |
| Order | Exhibit both long-range and short-range order. | Exhibit only short-range order. |
| Melting point | They have a sharp melting point. | They melt over a range of temperatures. |
| Heat of fusion | Show definite heat of fusion. | Do not have definite heat of fusion. |
| Clearage property | They undergo a clean clearage. | They cut irregularly. |
| Physical property | Show anisotropy in physical property measurements. | They are isotropic. |
| Nature | They are true solids. | They are pseudo solid or supercooled liquid. |
