1. Properties and classification of matter

2. What is matter?

3. 6 • We will be studying states of matter: • solids • liquids • gases • There is also plasma, liquid crystal and Bose-Einstein condensates

4. Mass – the quantity of particles in a substance - mesured in kg or pounds –the quantity of space occupied by a substance - mesured in cm3 or mL Volume Solids Liquids

5. SOLIDS • The particles are very close together • There is a high force of attraction between the particles

6. SOLIDS • Possess a definedmass (does not change) Possess a definedform (does not change)

7. SOLIDS • The particles don’t spread out in a container • Cannot be invisible The particles don’t move around, but they can vibrate. The force of gravity is always pushing on the particles.

8. LIQUIDS • The particles are close together, but there is space between them. The force of attraction between the particles is less than that of solids. The particles can easily move around.

9. LIQUIDS • Possess a defined mass Possess a defined volume

10. LIQUIDS • The particles spread out in a container (they take the container’s form, so their form is indefinite). • Cannot be invisible Particles can move easily

11. GASES • The particles are very spread out. • Possess an undefined volume. The force of attraction is very small, as is the force of gravity.

12. GASES • Possess an undefinedmass (as the particles are always moving) Possess an undefinedform (take the form of their container) ???

13. GASES • The particles spread out in a container (take its form) • Can be invisible The particles can easily move around

14. Review: Solids • Mass? • Volume? • Form? • Attraction? • Particles? • Invisible? • Take the form of the container? defined defined defined high close together no no

15. Review: Liquids defined • Mass? • Volume? • Form? • Attraction? • Particles? • Invisible? • Take the form of the container? defined undefined somewhat attracted somewhat spaced out no yes

16. Review:Gases • Mass? • Volume? • Form? • Attraction? • Particles? • Invisible? • Take the form of the container? undefined undefined undefined a little spread out yes/no yes

17. Review: Solid, Liquid and/or Gas??

18. Review: Solid, Liquid and/or Gas?? Particles move quickly Gas

19. Review: Solid, Liquid and/or Gas?? Particles only vibrate Solid

20. Review: Solid, Liquid and/or Gas?? Takes the form of its container Gas and Liquid

21. Review: Solid, Liquid and/or Gas?? The particles are very spread out Gas

22. Review: Solid, Liquid and/or Gas?? Defined mass Solid and Liquid

23. Review: Solid, Liquid and/or Gas?? Very little attraction between the particles Gas

24. Review: Solid, Liquid and/or Gas?? Does not take the form of its container Solid

25. Review: Solid, Liquid and/or Gas?? Defined masse and volume Solid and Liquid

26. Review: Solid, Liquid and/or Gas?? Not affected by gravity Gas

27. Review: Solid, Liquid and/or Gas?? Defined masse, defined volume, undefined form Liquid

28. Review: Solid, Liquid and/or Gas?? Undefined Volume Gas

29. Review: Solid, Liquid and/or Gas?? Strong attraction between particles Solid

30. Review: Solid, Liquid and/or Gas?? Particles can move around Gas and Liquid

31. Review: Solid, Liquid and/or Gas?? Defined masse, defined volume, defined form Solid

32. The particle theory of matter - See page 156 of Science Power 9

33. Plasma • Exists at very high temperatures • Exists in nature • Used in atomic lasers • Examples: • The Sun’s nucleus • Stars • Flashes of lightning

34. Plasma!!

35. Bose-Einstein Condensates • The lowest state of matter • Exists at very cold termperatures only • Absolute Zero (0°Kelvin = -273 °Celsius) • All particle movement stops • A SUPER SOLID is formed!!

36. Bose-Einstein Condensate

37. CONDENSATION SOLIDIFICATION SUBLIMATION EVAPORATION MELTING Bose-Einstein Condensate

38. Properties of Matter

39. The classification of matter

40. Matter Mixtures Pure Substances

41. Pure Substances • A pure substance pure is made up of one type of particle (atoms or molecules) • Water • Chlorine • Oxygen

42. Mixtures • Contain 2+ different types of particles that do not chemically react. They maintain their chemical characteristics but their physical properties may change. • Can be heterogenous or homogenous • Examples: • Sugar and water • Salt and pepper • Gold ring • Diet Coke

43. Pure substances Mixture Element Compound Homogeneous Heterogeneous All particles are identical. There is more than one type of particle

44. Matter Mixtures Pure Substances Mechanical Mixtures Solutions

45. Types of Mixtures

46. Classify the Mixture

47. Classify the Mixture DietPepsi Heterogenous
