Matter

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.

Presentation Transcript

  1. 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

  2. Some properties of matter include hardness, texture, shape, temperature, flammability, size and color. Can matter change properties?

  3. 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

  4. Solids, liquids and gases are the 3 principle states of matter. www.learnnc.org/.../ThreeStatesofMatter.jpg

  5. 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

  6. 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

  7. 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

  8. When can matter change its state? Matter can change its state whenever thermal energy is added or taken away.

  9. 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

  10. Evaporation Vaporization that takes place only on a liquid’s surface.

  11. Melting When thermal energy is added to a substance its particles vibrate faster until they break free from each other and the solid becomes a liquid.

  12. Melting Point Each substance melts at its own temperature called its melting point.

  13. Freezing When thermal energy is removed from a substance its particles slow down and the liquid changes to a solid.

  14. Vaporization A liquid gains enough thermal energy to become a gas.

  15. Boiling When vaporization takes place throughout a liquid.

  16. 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.

  17. Elements are pure substances that can not be broken down into other substances by physical or chemical changes. www.corrosionsource.com/.../periodic_table.gif

  18. 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...

  19. 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.

  20. 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.

  21. 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

  22. 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...
