Question

Which of the following is not the characteristic of a crystalline solid?

• A. Definite and characteristic heat of fusion
• B. Isotropic nature
• C. A true solid
• D. All of these

Answer 1

Answer: (B)

Isotropic nature

Crystalline solids are anisotropic in nature. This means the crystalline solids can change values of physical properties when measured in different directions. For isotropic solid material, physical properties are independent of the orientation of the system. Hence option B is the correct answer.
