Distinguish between crystalline solid and amorphous solid.
Crystalline solid | Amorphous solid |
1. Crystalline solids have a regular internal arrangement of particles. | 1. Amorphous solids have irregular arrangements of particles. |
2. They have a sharp melting point. | 2. Amorphous solids have no particular temperature value. |
3. These solids are regarded as true solids. | 3. Amorphous solids are regarded as pseudo solids. |
4. Crystalline solids undergo regular cleavage. | 4. These solids undergo irregular cleavage. |
5. These are more rigid. | 5. Amorphous solids are not much rigid. |
6. Anisotropic in nature i.e. solids in which the properties are different in all directions. | 6. Isotropic in nature i.e. Solids in which all the properties are uniform and are independent of direction. |
7. Example: Potassium nitrate, copper etc. | 7. Example: Cellophane, polyvinyl chloride etc. |
