Direct conversion of solids into vapours is called ___________________?
Correct answer: B. sublimation
- A. Solvent extraction
- B. sublimation
- C. crystallization
- D. vaporization
Explanation
Sublimation is the direct conversion of a solid into vapour without passing through the liquid state. Students may choose vaporization because it also forms a vapour, but vaporization usually refers to liquid changing into gas, whereas sublimation begins with a solid.

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.
