Mixtures Quiz

What is a heterogeneous mixture?

• A heterogeneous mixture is a mixture that consists of only one substance.

• A heterogeneous mixture is a mixture that consists of invisible substances or phases.

• A heterogeneous mixture is a mixture that consists of substances that are chemically combined.

• A heterogeneous mixture is a mixture that consists of visibly different substances or phases.

Give an example of a homogeneous mixture.

• sugarwater solution

• saltwater solution

• oil and vinegar dressing

• chocolate chip cookie

What is distillation used for?

• Filtering liquids

• Purifying gases

• Separating mixtures of liquids

• Mixing solids

How does evaporation separate mixtures?

• Evaporation converts the solid component into a gas, leaving behind the liquid or dissolved components.

• Evaporation separates mixtures by breaking down the solid or dissolved components into smaller particles.

• Evaporation converts the liquid component into a gas, leaving behind the solid or dissolved components.

• Evaporation causes the liquid and solid components to mix together, creating a new substance.

What is the purpose of filtration?

• To mix solids with liquids or gases.

• To remove impurities from solids, liquids, or gases.

• To convert solids into liquids or gases.

• To separate solids from liquids or gases.

Which type of mixture has visibly different substances?

• heterogeneous mixture

• element

• pure substance

• homogeneous mixture

Name a common example of a homogeneous mixture.

• oil

• sand

• milk

• saltwater

What happens during distillation?

• During distillation, a liquid mixture is heated to create vapor and then cooled to collect the condensed liquid.

• During distillation, a liquid mixture is frozen to separate the different components.

• During distillation, a liquid mixture is stirred to mix the components evenly.

• During distillation, a liquid mixture is filtered to separate impurities.

What is the main difference between evaporation and distillation?

• Evaporation is a natural process, while distillation is a controlled process involving heating and cooling.

• Evaporation involves heating and cooling, while distillation is a spontaneous process.

• Evaporation is a man-made process, while distillation is a natural process.

• Evaporation is used to separate mixtures, while distillation is used to purify substances.

Why is filtration important in separating mixtures?

• Filtration is important in separating mixtures because it allows for the separation of solid particles from a liquid or gas by passing the mixture through a filter medium.

• Filtration is a slow and inefficient method of separation.

• Filtration only separates liquid mixtures, not solid or gas mixtures.

• Filtration is not important in separating mixtures.
