I bragged to my dad about my presentation. When I went to show him the presentation on his work computer from SlideShare, I had uploaded the wrong powerpoint. That's why the date's wrong. I just got the chance to go online. I hope you like it! I spent a lot of time on the presentation. :)

  • Mr. McCarthy, the whole presentation isn't showing up. What should I do?

Kinetic Theory Of Matter

  1. 1. By Emily Adamson
  2. 2. What’s the Kinetic Theory of Matter? It’s a theory that helps explain difference between the states of matter.
  3. 3. The Kinetic Theory of Matter states… Matter is made up of constantly moving molecules or atoms.
  4. 4. Under the Kinetic Theory of Matter… Solids’ particles are so close to each other that they only vibrate in place.
  5. 5. Under the Kinetic Theory of Matter… Liquids’ particles have more space to move than solids, but there is still an attraction between them.
  6. 6. Under the Kinetic Theory of Matter… Gases’ particles are far apart and move around because the attraction is so low it can be disregarded.
  7. 7. Substances can change into different phases of matter and back. WHY DOES THIS HAPPEN?
  8. 8. First, we need to know about…. Kinetic Energy is energy of motion. There are multiple forms, such as:  Vibrational  Rotational  Translational.
  9. 9. First, we need to know about…. Thermal energy is total kinetic energy of all of a substance’s atoms and molecules .
  10. 10. First, we need to know about…. Temperature is the average amount of kinetic energy in an object.
  11. 11. Matter can change into different phases because the exchange of thermal energy between a substance and the environment.
  12. 12. Everything wants to be in its lowest state of energy. That’s why the exchange occurs!
  13. 13. • Increases as temperature increases • Increases as kinetic energy increases Thermal Energy • Increases as kinetic energy increases Temperature • Increases as thermal energy increases • Motion increases as temperature increases • Increases as thermal energy increases Kinetic Energy
  14. 14. Overall, when temperature increases, atoms and molecules’ motion increases (kinetic energy). Thermal energy increases because the total amount of kinetic energy increased due to the temperature change. THEY’RE ALL INTERTWINED!
