Choose the anisotropic behavior
Correct answer: A. Coefficient of thermal expansion
- A. Coefficient of thermal expansion
- B. Lattice energy
- C. Viscosity
- D. Infrared spectroscopy
Explanation
Anisotropy is the property of a material which allows it to change or assume different properties in different directions so the correct option is A i.e coefficient of thermal expansion as there are 3 coefficients i.e for volume, area and linear expansion

About Crystalline and Amorphous Solids
Crystalline solids have a regular, repeating lattice and a sharp melting point, while amorphous solids lack long-range order and soften over a temperature range. The topic covers unit cells, anisotropy, cleavage, symmetry and examples such as salts, metals, glass and plastics. Crystalline order must not be confused with mere hardness.
