### Matter and Its Properties

matter

Everything that takes up space and has mass is

Matter

This includes:

You

Air

Everything that you can taste, smell, or touch is matter.

What is not matter?

Anything that exists without taking up space.

• Heat
• Light
• Ideas
Mass

Mass is the amount of matter that something contains.

All matter is made up of tiny particles.
• The more particles an object has, the more mass it has.
• The more mass it has, the heavier it is.
Physical Properties

An object’s:

• Mass
• Look
• Texture
• Color
• State (liquid, solid or gas)
• Ability to transfer heat/electricity
Volume and Density
• Volume is the amount of space matter takes up.
• Density is the amount of matter in an object compared to the space it takes up.
States of Matter
• Solid
• Liquid
• Gas
• Plasma
Solid

In a solid, the particles are packed together in a tight pattern.

This gives solids an exact shape.

Particles in matter are always moving but in solids they are packed too tightly to move around much so they vibrate instead.

Liquids

Particles in liquids have more movement.

They take the shape of their container.

Gas

A Gas has no definite shape or volume.

The particles are far apart and move fast.

Plasma
• Similar to gas
• Some of the particles are ionized (have lost or gained electrons) making it charged
• It does not have a definite shape or volume unless closed in a container
• It is the most common state of matter in the universe
Examples of Artificially Produced Plasma
• Plasma TV
• Fluorescent Lamps (made of mercury vapor)
• Neon Signs
Examples of Terrestrial Plasma
• Lightning
• Aurora Borealis (lights display in the sky of Arctic and Antarctic caused by the collision of energetic charged particles with atoms in the high altitude atmosphere)
• Most Flames – gaseous part of fire
Examples of Astrophysical Plasma
• The sun and other stars (plasma heated by nuclear fusion
• Solar Wind ( a stream of charged particles ejected from the upper atmosphere of the sun)
• Interplanetary medium (space between planets)
• Interstellar medium (space between stars)
• Intergalactic medium (space between galaxies)
Mixtures

A mixture is two or more substances that are combined without being changed.

Example –

A salad is a mixture of solids

Salt water is a mixture of a solid and liquid

Fog is a mixture of water drops and air.

Solutions

A Solution is a mixture where different kinds of matter are completely mixed with each other.

Example:

Salt water

air

Solubility

Solubility is a measure of how much of one material will dissolve in another.

Suspension

A mixture where some of the ingredients are suspended or floating in the other.

Elements

There are more than 100 basic kinds of matter called elements.

Elements are the basic building blocks of matter.

Elements combine to make up all other kinds of matter.

Elements cannot be broken into smaller pieces with ordinary physical or chemical processes.

Most elements are combined to make the things we see.

For example: Rust is a combination of iron and oxygen.

Living and nonliving things are made up of just a few elements combined in different ways.
Chemical and Physical Properties of an element

Each element has its own chemical and physical properties.

These properties can be used to identify each element.

Metals

More than ¾ of the elements are called metals.

Metals have the physical properties of being:

• Shiny
• Bendable
• Able to conduct heat/electricity
