(a)Amorphous solids neither have ordered arrangement (i.e. no definite shape) nor have sharp melting point like crystals, but when heated, they become pliable until they assume the properties usually related to liquids. It is therefore they are regarded as super-cooled liquids.
The Solid State
31894
Silicon is
1 Semiconductor
2 Insulator
3 Conductor
4 None of these
Explanation:
(a)Silicon is a semiconductor because it is a thermal active and its conductivity increased with increasing temperature.
The Solid State
31895
Which of the following statements about amorphous solids is incorrect
1 They melt over a range of temperature
2 They are anisotropic
3 There is no orderly arrangement of particles
4 They are rigid and incompressible
Explanation:
(b)Amorphous solids are isotropic, because of these substances show same properties in all directions.
The Solid State
31896
The ability of a given substance to assume two or more crystalline structure is called
1 Amorphism
2 Isomorphism
3 Polymorphism
4 Isomerism
Explanation:
(c)Polymorphism is a ability of a substances which show two or more crystalline structure
The Solid State

Glass is
1 Supercooled liquid
2 Crystalline solid
3 Amorphous solid
4 \((a)\) and \( (c)\)
Explanation:
\((d)\) Amorphous solids neither have ordered arrangement (i.e. no definite shape) nor have sharp melting point like crystals, but when heated, they become pliable until they assume the properties usually related to liquids. It is therefore they are regarded as super-cooled liquids.
