Question

Differentiate between crystalline and amorphous solid.

Answer 1

1) Amorphous means “without form or structure".

In amorphous solid atoms and molecules are not organized in a definite lattice pattern. For example plastic, gel or glass.

Crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

2) Amorphous solids do not have definite melting points.

Crystalline solids have definitive melting point.

Answer 2

DIFFERENCE BETWEEN CRYSTALLINE AND AMORPHOUS SOLIDS :

Amorphous solids do not have definite melting points but melt over a wide range of temperature because of the irregular shape. Crystalline solids, on the other hand, have a sharp melting point.
