Melting point of crystalline solids are
Correct answer: A. Fixed
- A. Fixed
- B. Variable
- C. Have a range of value
- D. None of these
Explanation
Option A is correct since crystalline solids have a sharp melting point which is fixed. This feature is a characteristic of crystalline solids. Option B is incorrect since it shows the characteristics of amorphous solids. Option C is incorrect since it shows that the crystalline solid is impure. Option D is incorrect since it states none of these which is not the case.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
