6. WHAT WORD DESCRIBES MOTION OR MOVEMENT ENERGY?

7. KINETIC ENERGY All matter’s particles are in constant motion

8. State of Matter is determined by Particle arrangement Energy of particles Distance b/w particles

9. KINETIC THEORY: SOLIDS Atoms are vibrating on a fixed point in a solid

11. Amorphous Solid Has no organized internal structure Rubber Plastic Glass Asphalt Cotton Candy

12. COMPOUNDS WITH THE HIGHEST MELTING POINTS ARE….

13. Melting Points Strongest ( highest): Ionic Bonding Hydrogen Bonding Dipole-Dipole Lowest ( weakest) Dispersion

14. 1. Ionic : strongest bond Bond kept together by…. Crystalline structure

15. Covalent Compounds have three interactions( intermolecular forces) that keep them together….

16. 2. Hydrogen Bonding strongest covalent Highest MP & BP of covalent Hydrogen attracted to: N itrogen O xygen F luorine

17. 3. Dipole-Dipole [polar]  - end attracted /// to  + end of another

18. 4. Dispersion [nonpolar] weakest -a dipole is induced -lowest MP & BP interaction Induced  + Induced  -

19. KINETIC THEORY: LIQUIDS Particles are not bound together in fixed positions, but there is still some attractive forces keeping them close during movement.

20. Fluidity Particles flow, slide over each other

21. Viscosity 1. What was the difference between the two? 2. What do you think viscosity means?

22. KINETIC THEORY OF GASES Book clip: clip hereclip here

23. Gas Particles Assumption #1: Have a small volume Far apart from each other Independent : No attractive or repulsive forces

24. Gas Particles Assumption #2: Move: Rapid Independent Random Straight paths Only  direction when rebounding

25. Gas Particles Assumption #3 When particles collide, there collisions are elastic: no loss of energy it is transferred between the particles

26. GAS PRESSURE Force exerted when gas particles collide: click here click here

27. Pressure Units SI unit : Pascal (Pa) ▫ Sea level: 101.3 kPa Millimeters of Mercury: mm Hg ▫ blood pressure Atmospheres: atm ▫ Atmospheric pressure Torr Pounds per Square Inch: PSI ▫ Tire pressure, scuba diving Bar ▫ Atmospheric pressure

28. Conversions of Pressure 1 atm = 760 mmHg = 101.3 kPa 1 torr = 1 mm Hg 1 atm = 14.7 PSI 1 bar = 1 atm

29. Practice Converting A gas has a pressure of 1.50 atm. Convert to: a. Kilopascals b. Millimeters of mercury c. Pounds per Square Inch d. Torr e. Bar Show teacher work with answers
