Question

Difference between crystalline and amorphous solids show tables notes

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 !!

Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Crystalline :}$


1) Particles are arranged regularly.

2) Have smooth cut.

3) Have sharp melting point.

4) Have definite heat fussion.

5) They are true solid.

6) Ex :- All ionic solids like NaCl.


$\huge\textbf{Amorphous :}$

1) Particles are arranged irregularly.

2) Have rough cut.

3) Have range of melting point.

4) Have indefinite heat of fussion.

5) They are super cooled liquid.

6) Ex :- Glass, rubber etc.
