1 4 What Are The 3 States Of Matter

  1. 1. Launch: 1/4   Grab your binder and immediately take a seat!   On the folder, write your   first name   last name   block #   Carefully empty the contents of binder into the folder   Make sure it stays organized!   Objective: I can describe the properties of the three states of matter
  2. 2. New Changes for the New Year!   Late homework policy   Late homework in now due the day after you return   It is your responsibility to get it stamped the day after you return, or no credit!   Notes packets, handouts, and practice questions will can be found:   online (lpschem.wordpress.com)   at the back of the classroom   You are still responsible for taking notes!   Absent students will be omitted from class points
  3. 3. New Changes for the New Year!   Class consequences 1.  Name on board stay outside 2.  Take a break within 5 feet of the door until 3.  Call home called in by Mr. 4.  Sent to Mr. Wandera Heffner
  4. 4. Same Old, Same Old   Class rules   PAT Time   Big Goal!
  5. 5. What are the 3 states of matter? Mr. Heffner 1/4/10
  6. 6. What are the 3 states of matter?   Molecules want to bounce around randomly   But, attraction between molecules can sometimes make them stick together   inter = between intermolecular attraction
  7. 7. What are the 3 states of matter?   Because of intermolecular attraction, matter can exist in 3 different states Solid Liquid Gas
  8. 8. What are the properties of gases?   Gases:   No intermolecular attractions   Random movement   Really fast!   Example: steam Gas
  9. 9. What are the properties of liquids?   Liquids:   Weak intermolecular attractions   Random movement   Slow   Example: water Liquid
  10. 10. What are the properties of solids?   Solids:   Strong intermolecular attractions   Molecules stuck in ordered arrangement   Don’t move   Example: ice Solid
  11. 11. Oobleck!   Work in a group of four   Take turns playing with the Oobleck   As a group discuss: Is Oobleck a solid, a liquid, or a gas?   Have recorder take out a half sheet of paper   Write names   In 3-4 sentences, answer the discussion question.   Your answer should include and explanation of why your group came to that decision   Be sure to get feedback from all group members
  12. 12. Oobleck!   Oobleck is…   a non-Newtonian liquid
  13. 13. Exit Slip 1.  Which of the following are states of matter? Intermolecular Gas Liquid attraction I II III a.  I only b.  I and II c.  III only d.  I and III
  14. 14. Exit Slip 2.  Which of the following is an example of a solid? a.  milk b.  ice c.  the air d.  water
  15. 15. Exit Slip 3.  Molecules in a solid are held together because of a.  a strong intermolecular attraction to neighboring molecules. b.  a weak intermolecular attraction to neighboring molecules. c.  a weak electrostatic attraction between anions and neighboring cations. d.  no intermolecular attraction to neighboring molecules.
  16. 16. Exit Slip 4.  Unlike liquids, the molecules in gases a.  do not move randomly. b.  move randomly but have strong intermolecular attractions. c.  are usually opaque in color. d.  move very fast and are not attracted to other molecules.
  17. 17. Exit Slip 5.  In which of the following substances would the molecules have the most amount of random movement? a.  water b.  ice c.  steam d.  a chair
  18. 18. Homework   Finish practice questions
