Without suction pump filtration is __________________?
Correct answer: B. Slow process
- A. Fast process
- B. Slow process
- C. Rapid process
- D. All are possible
Explanation
Without a suction pump, filtration is driven only by gravity and therefore takes place relatively slowly. Students may choose fast or rapid because filtration itself is a separation method, but suction is what increases the pressure difference and speeds the process.

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.
