Water Filtration Process Concepts

The video tutorial demonstrates the process of filtration. It begins with folding a round filter paper into a cone and placing it in a funnel fixed on a stand. The sides of the funnel are wetted to ensure the filter paper stays in place. Muddy water is then poured through the filter paper, and clear water, known as the filtrate, is collected in a beaker below. This method of purifying water is called filtration.

What is the first step in preparing the filter paper for filtration?

• Roll the filter paper into a cylinder

• Tear the filter paper into small pieces

• Fold the filter paper into halves to form a cone

• Cut the filter paper into quarters

Where should the filter paper be placed after folding it into a cone?

• In a beaker

• On a flat surface

• Inside a funnel

• In a test tube

What happens to the muddy water when it is poured through the filter paper?

• It becomes clear water

• It turns into steam

• It remains muddy

• It evaporates

What is the clear water collected in the beaker called?

• Residue

• Filtrate

• Solvent

• Distillate

What is the name of the method used to purify water in this process?

• Evaporation

• Sedimentation

• Filtration

• Distillation
