2. A physical combination of two or more kinds of matter is called a mixture.

3. Each kind of matter in a mixture keeps its own chemical properties.

4. Many everyday products, including the food you eat and the clothing you wear, are mixtures

5. A mixture that is blended completely is called a solution.
saltwater

6. Salt water is a good conductor of electricity.

7. A solution might have properties that the original materials did not have.

8. Bronze is an alloy made of copper and tin.
A mixture of two or more metals or a metal and a nonmetal is called an alloy.
Bronze is an alloy made of copper and tin.

9. The materials in a mixture can be separated by using their physical properties.

10. Solids are often separated from a liquid by using a filter.

11. Using a filter to separate a mixture is called filtration.

12. A mixture containing certain metals can be separated using a magnet.

13. Salt crystals left behind after the evaporation of salt water.
Solids can be separated from a solution by using evaporation; the liquid part of the solution is lost to the air.
Salt crystals left behind after the evaporation of salt water.

14. Liquid water can be collected from a solution of salt water by distillation.

15. Alloys- mixtures of metals that can be stronger than the original.
Food- mixtures that may taste better together than by themselves.
Magnets can be used to separate mixtures.
