• Pour the mixture through filter paper.

• Stir the mixture until the sand dissolves.

• Heat the mixture until the water evaporates.

• Freeze the mixture to separate the sand.

What is the process of separating a mixture of an insoluble solid and a liquid called?

• Distillation

• Filtration

• Evaporation

• Condensation

How does filtration work to separate a mixture of an insoluble solid and a liquid?

• By heating the mixture to evaporate the liquid.

• By pouring the mixture through a filter paper.

• By cooling the mixture to freeze the liquid.

• By stirring the mixture until the solid dissolves.

Why is it important to use a funnel when performing filtration?

• To prevent spillage of the mixture.

• To ensure all of the liquid is collected.

• To hold the filter paper securely in place.
