Question

Which of the following are the characteristics of an amorphous solid?
A. Short range order
B. Sharp melting point
C. Isotropic in nature
D. Definite heat of fusion

• A. A,D
• B. A,C
• C. A,C,D
• D. B,D

Answer 1

The correct option is B A,C

Amorphous solids consist of particles of irregular shape, so it displays short range order.
Amorphous solids soften over a range of temperature, and hence doesn’t show sharp melting point.
The value of a physical property will be same from any directions in case of amorphous solids. So, they are said to be isotropic in nature.
Amorphous solids do not have a definite heat of fusion.
