Amprphous Solids


Crystalline Solids


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.
