Advertisements
उत्तर
| Crystalline solids | Amorphous solids |
| They have long range order i.e there is regular arrangement of molecules over a long distance. | They have short range order i.e there is regular arrangement of molecules over a short distance only. |
| They are anisotropic i.e the value of physical properties will be different when measured along different directions | They are isotropic i.e they will show same values of all physical properties when measured along different directions |
