Question

Write any three difference between crystalline and amorphous solids

Answer 1

1. Crystalline solids have a regular three dimensional arrangement of atoms, ions or molecules due to which they have well defined geometrical shape.


Amorphous solids do not have regular arrangement of particles, therefore do not have well defined particles.

2.

Crystalline solids are anisotropic, i.e., they have different optical and electrical properties in different directions.

Amorphous solids are isotropic, i.e., they have same properties in all directions.


3.
Crystalline solids are true solids, i.e., they show all the characteristic properties of solids.

Amorphous solids are pseudo – solids, i.e., they do not show all the characteristic properties of solids.


Hope it helps

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 !!
