Question

Which of the following statements about amorphous solids is incorrect?

• A. They melt over a range of temperature
• B. They are anisotropic
• C. There is no orderly arrangement of particles
• D. They are rigid and incompressible

Answer 1

The correct option is B They are anisotropic

Amorphous solids are characterised by Isotropic nature, short-range order (exhibit definite arrangement of particles only for a small range), diffuse melting point, inability to exhibit X-ray diffraction, lack of centre, axes or planes of symmetry, have uniform refractive index, thermal properties throughout and do not exhibit variation in these properties on changing the viewpoint.

Amorphous solids are isotropic, because of these substances show same properties in all directions.
