Question

What are the differences between amorphous solid and crystalline solids?

Answer 1

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 !!
