Question

what is the difference between crystalline solid and amorphus solid

Answer 1

Amorphous solids don't have particular melting point. They melt over a wide range of temperature. Physical properties of crystalline solids are different in different directions. This phenomenon is known as Anisotropy.

Answer 2

Hey !!

CRYSTALLINE SOLIDS

• Definite characteristics and geometrical shape.
• Melt at a sharp and characteristic temperature.
• When cut with a sharp edged tool, they split into two pieces and the newly generated surfaces are plain and smooth.
• They have a definite and characteristic heat of fusion.
• Anisotropic in nature.
• True solids.
• Long range order.

AMORPHOUS SOLIDS

• Irregular shape.
• Gradually soften over a range of temperature.
• When cut with a sharp edged tool, they cut into two pieces with irregular surfaces.
• They do not have a definite heat of fusion.
• Isotropic in nature.
• Pseudo solids or super cooled liquids.
• Only short range order.

GOOD LUCK !!
