Question

list any four properties of crystalline and amorphous solids​

Answer 1

Answer:

Explanation:

Difference between Crystalline and Amorphous Solid

Properties Crystalline solid Amorphous solid

Structure The constituent particles, atoms, ions or molecules are arranged in regular and definite three dimensional patterns. For example, sodium chloride, diamond, sugar etc. The constituent particles are arranged in irregular three dimensional patterns.

Cutting with a knife Gives clean, sharp cleavage. Unclean cleavage.

Compressibility Rigid and incompressible Usually rigid and can not be compressed to any appreciable extent.

Melting point They have a sharp and definite melting point. Melting point is not definite. Melt over a range of temperatures.

Heat of fusion Definite Not definite.

Physical properties These are anisotropic in that their physical properties are not identical in all directions. These are isotropic, that is their physical properties are identical in all directions.
