(evenly mixed)
• A solution forms when one substance dissolves in another.

• When a substance dissolves, it breaks into tiny particles that can’t even be seen with a microscope.
• These particles evenly mix with the other parts of the solution.
• Not all substances can dissolve. For example, if you put a rock and salt in water, the rock won’t dissolve but the salt will.

• Many solutions are liquids.
• Some solutions are gases or solids.
• For example, air is a solution of tiny particles of nitrogen, oxygen, and other gases.(gas)
• Brass is a solid solution.

Separating Mixtures
Copyright © Houghton Mifflin Harcourt Publishing Company
• A mixture can be separated. Each component in a mixture keeps most of its physical properties.
• Physical properties such as color, size, melting point, boiling point, density, and ability to dissolve can be used to separate mixtures.
• Mixtures can be easy or difficult to separate.

• A sieve, or mesh screen, has
holes that matter can pass through. Smaller matter passes through the screen while larger matter stays in the sieve.
• A magnet attracts matter that contains iron, separating it from the other parts of the mixture.

• Filters have tiny openings, or pores, where only the smallest bits of matter, like water particles, can pass through.
• Boiling changes a liquid to a gas at the liquid’s boiling point. Evaporation changes a liquid to a gas below the liquid’s boiling point.
• During boiling and evaporation, liquid particles leave the solution while dissolved particles stay behind.

• Mixtures can have different properties depending on the amounts of each ingredient.
• An alloy is a mixture of metals and other substances.
• Steel is an alloy made from iron and other substances.

• Different substances give steel different properties.
• Adding chromium makes steel shiny.
• Metals such as nickel and titanium can keep steel from rusting.
• Adding carbon can make steel stronger.
