Which of the following describes the formation of a solution?

• A. A substance melts in another substance, forming a solution.

• B. A solid substance floats on top of a liquid substance, forming a solution.

• C. A substance breaks down into tiny pieces in another substance, forming a solution.

How are a mixture of sand and water and a mixture of salt and water different?

• A. Sand melts in the water. Salt dissolves in the water.

• B. Sand floats in water. Salt sinks in water.

• C. Sand dissolves in water. Salt does not dissolve in water.

• D. Salt dissolves in the water. Sand does not dissolve in water.

How can you separate a mixture of sand, salt, and water?

• A. Use a paper filter to separate the sand from the rest of the mixture. Then, boil the saltwater in a pot. The salt will remain in the pot and the water will evaporate.

• B. Evaporate the saltwater from the mixture, then use a paper filter to separate the salt from water. The water will pass through the filter.

• C. Evaporate the water from the mixture. Use a funnel to separate the sand from the salt.

• D. Use tweezers to separate the sand and salt from the water in the mixture.
