3. Kinetic Theory of Matter Matter is anything that has mass and takes up space. Mass is the amount of matter in an object. Matter is made up of particles which are in continual random motion.

4. STATES OF MATTER The Five States of Matter The Five States of Matter Solid Solid Liquid Liquid Gas Gas Plasma Plasma Bose-Einstein Condensate (BEC) Bose-Einstein Condensate (BEC)

5. STATES OF MATTER  Based upon particle arrangement  Based upon energy of particles  Based upon distance between particles

6. STATES OF MATTER SOLIDS Particles of solids are tightly packed, vibrating about a fixed position. Solids have a definite shape and a definite volume. Heat

7. STATES OF MATTER LIQUID  Particles of liquids are tightly packed, but are far enough apart to slide over one another.  Liquids have an indefinite shape and a definite volume. Heat

8. STATES OF MATTER GAS  Particles of gases are very far apart and move freely.  Gases have an indefinite shape and an indefinite volume. Heat

9. PHASE CHANGES Description of Phase Change Term for Phase Change Heat Movement During Phase Change Solid to liquid Melting Heat goes into the solid as it melts. Liquid to solid Freezing Heat leaves the liquid as it freezes.

10. PHASE CHANGES Description of Phase Change Term for Phase Change Heat Movement During Phase Change Liquid to gas Vaporization, which includes boiling and evaporation Heat goes into the liquid as it vaporizes. Gas to liquidCondensation Heat leaves the gas as it condenses. Solid to gasSublimation Heat goes into the solid as it sublimates.

11. Two states of matter they didn’t teach you about in school… Until Now!

12. But what happens if you raise the temperature to super-high levels… between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

13. NO! If the gas is made up of particles which carry an electric charge (“ionized particles”), but the entire gas as a whole has no electric charge, and if the density is not too high, then we can get The 4 th state of matter: PLASMA

14. STATES OF MATTER PLASMA  A plasma is an ionized gas.  A plasma is a very good conductor of electricity and is affected by magnetic fields.  Plasmas, like gases have an indefinite shape and an indefinite volume. Plasma is the common state of matter

15. Some places where plasmas are found… 1. Flames

16. 2. Lightning

17. 3. Aurora (Northern Lights)

18. The Sun is an example of a star in its plasma state

19. 5. Stars Stars make up 99% of the total matter in the Universe. Therefore, 99% of everything that exists in the entire Universe is in the plasma state.

20. 4. Neon lights

21. 6 6. Clouds of gas and dust around stars

22. But now what happens if you lower the temperature way, way, down to 100 nano degrees above “Absolute Zero” (-273°C) Will everything just be a frozen solid?

23. Not Necessarily! In 1924 (90 years ago), two scientists, Albert Einstein and Satyendra Bose predicted a 5 th state of matter which would occur at very very low temperatures. EinsteinBose +

24. The 5 th state of matter: Bose-Einstein Condensate Finally, in 1995 (only 19 years ago!), Wolfgang Ketterle and his team of graduate students discovered the 5 th state of matter for the first time. Ketterle and his students

25. In 2002, Ketterle and two other scientists received the highest award in science for discovering Bose-Einstein condensate: The Nobel Prize

26. In a Bose-Einstein condensate, atoms can no longer bounce around as individuals. Instead they must all act in exactly the same way, and you can no longer tell them apart!

27. Some other computer images of Bose-Einstein Condensates…

28. STATES OF MATTER SOLID LIQUID GAS PLASMA Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles
