Question

main difference between crystalline and amorphous material is of

Answer 1

shape... crystalline have a definite shape like diamond but amorphous don't have a definite shape

Answer 2

Answer:-

Amorphous solids

• 1. There is only a short range order in amorphous solids
• 2. Amorphous solids do not have a sharp melting point; they are softened in a range of temperature.
• 3. Amorphous solids undergo irregular or conchoidal breakage.
• 4. Amorphous solids are isotrophic-the properties will be independent of the direction in which they are measured.
• 5. Less rigid.

Examples of Amorphous solids: Fibre glass, Cellophane, Teflon, Polyurethane, Naphthalene, Polyvinyl chloride

Crystalline solids

• 1. There is a long range order in crystals.
• 2. Melt at a sharp temperature.
• 3. Crystalline solids can be cleaved along definite planes.
• 4. Crystalline solids, in general are anisotrophic (It means that, their properties such as electrical conductivity, refractive index, thermal expansion etc. will be different directions).
• 5. More rigid.

Examples of Crystalline solids: Copper, Potassium nitrate, Benzoic acid
