States of Matter Jaime Taff firstname.lastname@example.org
States of Matter • Matter is anything that has mass and takes up space.
Solids • Solids are characterized by having a definite shape and volume, which means that if you put a solid in a container, it will not change its shape.
Particles of Solids • The particles in solids are closely pack together, which means that they do not have much room to move around. The particles also have a specific arrangement
Examples of Solids • Ice • Rocks
Liquids • Liquids have a definite volume, but not a definite shape. Liquids take the shape of the container they are put in.
Particles of Liquids • The particles in a liquid are close together, but not in a neat, even arrangements as the particles in a solid are. They can move/slide past each other easily.
Examples of Liquids • Water • Lemonade • Juice
Gases • Gases have no definite shape and no definite volume. If you put a gas into a container it will spread out and fill the container completely.
Particles of Gases • The particles that make up gases are spread apart, move fast, and have big spaces between them.
Examples of Gases • Air • Balloon filled with Helium
Changes of States of Matter • A change of state is when something such as water turns from being water to being ice. Each change is called something different.
Freezing • The process by which matter changes from liquid to solid. • Example: water to ice
Melting • The process by which a solid changes to a liquid. • Example: ice to water
Evaporation • The process by which liquid changes to a gas. • Example: water to steam
Condensation • The process by which a gas changes to a liquid. • Example: steam to water
Sublimation • The process by which a solid changes directly to a gas. • Example: solid carbon dioxide (dry ice) to gaseous carbon dioxide
Deposition • The process by which a gas changes directly to a solid. • Example: water vapor in the air during the winter falls as snow
