Answer 2

hello there once again.

Amorphous solids Crystalline solids

i. They have an irregular shape. They have a definite characteristic geometrical shape.

ii. They have only short-range order in the arrangement of constituent particles. They have long-range order in the arrangement of constituent particles.

iii. They gradually melt and soften over a range of temperature. They have sharp and characteristic melting points.

iv. When cut with a sharp-edged tool, they cut into two pieces with irregular shapes. When cut with a sharp-edged tool, they split into two pieces with plain and smooth newly-generated surfaces.

v. They do not have definite heat of fusion. They have definite and characteristic heat of fusion.

vi. They are isotropic in nature. They are anisotropic in nature.

vii. They are pseudo solids or super-cooled liquids. They are true solids.
