Transcript of "Chapter 11"

  1. 1. Chapter 11 Meet Matter Picture taken from: http://www.success.co.il/knowledge/images/Pillar3-Matter-and-Energy-Sun-NASA.jpg
  2. 2. What is matter?  Matter is anything that  1. Has mass and  2. Takes up space (has volume)
  3. 3. Biological Properties  Characteristics of matter that are unique to living things
  4. 4. Physical Properties  Anyproperty of matter that can be observed by your senses without changing the composition of the matter  Forexample you don’t have to change what an apple is made of to see that it’s red or to hold it in your hand
  5. 5. Physical Properties  You rely on physical properties all the time to identify or describe matter  Are your socks clean? (odor)  Can you fit all your books into your book bag? (volume)  Does your shirt match your pants? (color)  And many, many others
  6. 6. Chemical Properties  Any property of matter that describes a substance based on its ability to change into a new substance with different properties
  7. 7. Chemical Properties Example: Piece of wood can be burned to create  new substances (ash and smoke) with properties different from the original piece of wood. You can also observe chemical properties with  your senses but they aren’t as easy to observe as physical properties. Some chemical properties include flammability  (ability to burn), reactivity with oxygen, reactivity with acid, and reactivity with water. (Reactivity just means that when 2 substances get together, something can happen.)
  8. 8. Think/Pair/Share  Whatare the two properties of all matter?  What is the difference between physical and chemical properties?
  9. 9. With a Partner  Playa game of 20 Questions. One person will think of an object and the other person will ask yes/no questions about it. Write the questions down in your notebook as you go along. Put a check mark next to the questions asked about physical properties. When the object is identified or when the 20 questions are up, switch roles.
  10. 10. What would you say?  If you were asked to describe an orange to someone who had never seen an orange, what would you tell the person?
  11. 11. Matter  Anything that has mass and takes up space
  12. 12. Is Air Matter?
  13. 13. Molecule  The smallest particle of a substance, such as water, that is still identified as that substance
  14. 14. States of Matter Easily observed physical property of  matter.  At ordinary temperatures, all matter exists in one of three states. 1- Solid 2- Liquid 3- Gas  In each of these states the molecules of the material behave in different ways.
  15. 15. States of Matter The state of matter of a substance  depends on how fast the particles move and how strongly the particles are attracted to each other. Gas  Liquid  Solid 
  16. 16. Physical change  Anychange in matter that does not change the chemical properties of the matter.  Forexample, if you break a piece of chalk in two, you change the physical properties of size and shape. The chemical properties of the chalk remain unchanged.
  17. 17. Chemical change  A change in matter in which one substance is converted into another substance  Some examples: rusting, effervescent tablets, soured milk, burning
  18. 18. Chemical Properties vs. Chemical Changes  Chemical properties determine how substances interact with each other, while chemical changes are the result of the interaction  In other words: Chemical properties can result in chemical changes.
