Which of the following is not true for a crystalline substance?
Correct answer: B. no definite melting point
- A. short range order
- B. no definite melting point
- C. sharp melting point
- D. All
Explanation
Crystalline substances typically have a well-defined, sharp melting point. Therefore, the statement "No definite melting point" is not true for a crystalline substance.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
