Question

What type of filtration relies on gravity to pull liquid through the filter medium?

• A. Vacuum filtration
• B. Centrifugal filtration
• C. Gravity filtration
• D. Pressure filtration

Hint:

If a question mentions natural flow or no external force, think "gravity filtration" — it's slow but straightforward.

Answer 1

The Correct Option is C

Gravity filtration is a basic and commonly used filtration method where gravity alone is used to draw the liquid through the filter medium.
This method does not involve any external force like vacuum or pressure. Instead, it utilizes the gravitational pull on the liquid to make it pass through a filter paper or membrane.
This type of filtration is especially useful in simple laboratory setups and is ideal for removing suspended solids from liquids without requiring special equipment.
Vacuum, centrifugal, and pressure filtration all use external forces (vacuum suction, centrifugal force, or applied pressure, respectively) to speed up the filtration process.
