Science review for 1st nine weeks

Which process would you use to separate solid particles from larger particles in a mixture with filter paper in a funnel to trap solids so that the liquids will pass through.

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate magnetic material from a mixture of other substances?

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate and analyze the solutes in a solution. During this process bands of color form on filter paper to show the different substances in the solution.

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

What is a solute?

• different materials placed together but keeping their own properties

• a mixture in which substances spread out evenly and will not settle

• the degree to which a material will dissolve in another substance

• the substance in a solution that has the greatest amount

• the substance in a solution that has the least amount

Which process would you use to separate smaller solid particles from larger solid particles. A mixture of different sized solids is put into a container that has a screen material at the bottom with certain sized holes in it. The smaller particles go through the screen and the larger ones do not.

• Evaporation

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate a solid that has dissolved in a liquid solution. The solution is heated or left uncovered until the liquid turns to gas and leave the solid behind.

• Evaporation

• Magnetic Attraction

• Filtration

• Floatation

• Sifting
