|
1. Solids that don't have definite geometrical shape. |
They have characteristic geometrical shape |
2. Amorphous solids don't have particular melting point. They melt over a wide range of temperature. |
They have sharp melting point |
3. Physical properties of amorphous solids are same in different direction,i.e. amorphous solids are isotropic |
Physical properties of crystalline solids are different in different directions. This phenomenon is known as Anisotropy. |
4. Amorphous solids are unsymmetrical |
When crystalline solids are rotated about an axis, their appearance does not change. This shows that thay are symmetrical |
5. Amorphous solids don't break at fixed cleavage planes. |
Crystalline solids cleavage along particular direction at fixed cleavage planes. |
