Matter. Matter is anything that has mass and takes up space. It is the “stuff” that makes up everything in the universe. www.bcap.scot.nhs.uk/crop_3_balloon_copy.jpg . healthinmotion.files.wordpress.com/2007/07/aq. geology.com/rock-tumbler/clean-rocks.jpg.

Matter Matter is anything that has mass and takes up space. It is the “stuff” that makes up everything in the universe. www.bcap.scot.nhs.uk/crop_3_balloon_copy.jpg healthinmotion.files.wordpress.com/2007/07/aq... geology.com/rock-tumbler/clean-rocks.jpg image.guardian.co.uk/.../11/28/paperclip460.jpg
Some properties of matter include hardness, texture, shape, temperature, flammability, size and color. Can matter change properties?
Matter can change properties. What are some examples of matter changing properties? www.wildwoodchapel.com/.../campfire.jpg www.learner.org/.../images/s4.ice_melt2.jpg
Solids, liquids and gases are the 3 principle states of matter. www.learnnc.org/.../ThreeStatesofMatter.jpg
Solids have a definite volume and a definite shape. The particles are packed tightly together and stay in a fixed position. www.cofc.edu/.../111LectWeek1_files/image008.jpg
Liquids have no definite shape and instead, takes the shape of its container. Liquids have no definite shape but does have a definite volume. Particles of a liquid are free to move. www.cofc.edu/.../111LectWeek1_files/image008.jpg images.inmagine.com/.../cr15202/cr15202031.jpg
A gas has no definite shape or volume. Gas particles spread apart filling the space available. www.cofc.edu/.../111LectWeek1_files/image008.jpg www.dkimages.com/.../previews/845/60019752.JPG
Physical changes alter the form of a substance, but not its identity. Example: When you boil away a pan of water, the water is still present as vapor. www.clipartguide.com/.../0060-0502-2515-5358.jpg
Chemical changes occur when substances combine or break apart to form new substances. Example: Heating table sugar until it turns to caramel; burning wood until it turns into ash.
Elements are pure substances that can not be broken down into other substances by physical or chemical changes. www.corrosionsource.com/.../periodic_table.gif
Compounds are substances made of two or more elements that are chemically combined. Example: Water (H20) and Carbon Dioxide (CO2) upload.wikimedia.org/wikipedia/en/thumb/0/07/... jasonleggett.greenoptions.com/files/images/co...
Measuring Matter The temperature at which a liquid boils is called its boiling point. The temperature at which a solid melts is called its melting point.
The mass of an object measures how much matter the object contains. The weight of an object is a measure of the force of gravity on the object.
The amount of space that matter occupies is called its volume. Density is the amount of mass of a substance is contained in a given volume. library.thinkquest.org/.../cub_diagram_1.GIF
The formula for density: Density= Mass Volume Why does the concrete cube have greater mass than the equal-size air cube? www.legoeducation.com/sharedimages/content/La...
