Which of the following methods of separation are we going to use to separate two liquids with different boiling points?

• Magnetic Separation

• Filtration

• Evaporation

• Distillation

What is the difference between filtration and screening?

• Filtration is separating liquid from solid components while screening is separating solid mixtures with different particle size.

• Filtration is separating solid mixtures with different sizes while screening is separating liquid from solid components.

• Filtration is separating magnetic from non-magnetic substances while screening is separating immiscible from non-miscible mixtures.

• Filtration is separating liquids with different boiling points while screening is separating liquid from solid substances using filter.
