Question

differentiate between crystalline and amorphous substances in answer

Answer 1

crystalline 1.These are long rang order forces. 2.They have sharp melting point. Amorphous 1.these are short range order forces. 2.they have no sharp melting point

Answer 2

Crystalline Substances=

Definite characteristic 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 substances=

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 definite heat of fusion

Isotropic in nature

Pseudo solids or super cooled liquids

Only short range order
