Question

differentiate between the crystalline and amorphous solid

Answer 1

Crystalline - (1) are true solids (2) are those solids in which particles are arranged in regular and peroidic manner in 3-d space (3) have long range order (4) can be cut into clean surfaces (5) are made up of unit cell (6) have fixed or sharp melting point (7) have definite value for heat of fusion (8) are aniisotropic


Amorphous - (1) pseudo solids or supercooled liquids (2) particles not arranged in regular manner (3) short range orfer (4) not made up of unit cell (5) can not be cut into clean surfaces (6) do not sharp melting pt , they have melting range (7) do not have fixed value for heat of fusion (8) are isotropic

Answer 2

AMPRPHOUS :-
1) solids that don't have a definite geometrical shap .
2) Amorphos solid don't have over wide range of temperature .
3) Amorphous solids are unsymmetrical .
4) Amorphous solid don't break at fixed clevage planes .


CRISTALLINE :-
1) they have a characteristick of geometric shape .
2) they have a sharp melting point .
3) when christalline solid are rotated about an axis there appeareance dosnot change
4) christalline solid clevage along particular direction at a fixed clevage plane.
