Question

Distinguish between crystalline solid and amorphous solid.

Differentiate crystalline solids and amorphous solids.

In what respects, amorphous solids differ from crystalline solids? Explain.

Mention three differences between crystalline and amorphous solids.

Answer 1

Sr. No.	Crystalline solids	Amorphous solids
1.	The constituent particles are arranged in a regular, orderly pattern over a long range.	The constituent particles are arranged in a short-range or random manner.
2.	They have a definite geometric shape.	They have an irregular and indefinite shape.
3.	These solids are generally anisotropic, meaning their physical properties vary with direction.	These are isotropic, meaning their physical properties are the same in all directions, similar to liquids.
4.	They have a definite and sharp heat of fusion.	They do not have a definite heat of fusion.
5.	They are pure solids.	They are supercooled liquids.
6.	They have sharp and well-defined melting points.	They gradually soften over a range of temperatures and can be molded when heated.
7.	E.g., Ice, NaCl, diamond	E.g., Glass, rubber, plastics
