Separating Mixtures through evaporation, filtration and sieving.

What is evaporation?

• Evaporation is the process by which a liquid changes into a solid state.

• Evaporation is the process by which a liquid changes into a gas or vapor state.

• Evaporation is the process by which a gas changes into a liquid state.

• Evaporation is the process by which a solid changes into a liquid state.

What is the process of separating a solid from a liquid mixture by heating the mixture?

• condensation

• sublimation

• filtration

What is the purpose of using filter paper in filtration?

• To increase the rate of filtration.

• To change the pH of the filtrate.

• To separate solid particles from a liquid or gas.

• To remove impurities from a solution.

What happens to the solid component during filtration?

• The solid component dissolves in the filtrate.
