PGS. 456-463

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

mixture.

Each kind of matter in a mixture keeps its own chemical

properties.

Many everyday products, including the food you eat and

the clothing you wear, are mixtures

A mixture that is blended completely is called a solution.

saltwater

Salt water is a good conductor of electricity.

A solution might have properties that the original

materials did not have.

Steel is made by mixing iron and carbon. It is much stronger than the original iron.

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.

The materials in a mixture can be separated by using their

physical properties.

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

Using a filter to separate a mixture is called filtration.

A mixture containing certain metals can be separated using a

magnet.

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.

Liquid water can be collected from a solution of salt water by

distillation.

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.
