Sintered glass is a porous material used for ___________________?
Correct answer: C. filtration
- A. absorption
- B. adsorption
- C. filtration
- D. sublimation
Explanation
Sintered glass contains a fixed network of interconnected pores, allowing liquid or gas to pass while retaining solid particles. It is therefore used as a filtering medium, often avoiding loose filter paper or fibres. Students may choose b because porous surfaces can adsorb substances, but adsorption is not the main purpose here.

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.
