Question

Which of the following is NOT true about the amorphous solids ?

• A. Amorphous solids can be moulded by heating.
• B. On heating they may become crystalline on certain temperature.
• C. They are anisotropic in nature
• D. They may become crystalline on keeping for long time.

Answer 1

Answer: (C)

They are anisotropic in nature

Answer 2

The statement that is NOT true about amorphous solids is: (C) They are anisotropic in nature.
Amorphous solids do not have a well-defined long-range order like crystalline solids. They have a disordered arrangement of atoms or molecules, resulting in a lack of symmetry in their structure. Due to this lack of long-range order, amorphous solids exhibit isotropic properties, meaning their properties are the same in all directions. In contrast, crystalline solids have a well-defined periodic arrangement and can exhibit anisotropic properties, meaning their properties can vary depending on the direction.
Therefore, amorphous solids are NOT anisotropic in nature.
