Mabunda nc the states of matter

  1. 1. The States Of Matter EDITED BY: MABUNDA NC: 201106379 AUTHORS: BOYD C, Aurellia T, Devinda V.S, Deepti J, Einstein, B, Hoppenstein, B, MARTIN, J AND Stanley
  2. 2. Solid  Solid-The state of matter that has a definite volume and shape. The molecules move slow and stay in a square shape. They vibrate when they move.
  3. 3. Properties of solids  The particles are very close together because they have a very strong attraction for each other.  Since they are so close, they cannot move around. So they just vibrate in place.
  4. 4. Solids
  5. 5. When a solid is heated it expands. For example, when it is cool a metal bar fits inside a metal gauge. When the bar has been heated it will no longer fit in the gauge or in the hole. And when it cools down it will fit in the gauge and hole again.
  6. 6. Liquid (cont.)  There are Two properties in the liquid matter  1.Surface Tension-the force that act on particles on the surface  2.viscosity- A liquid resistance to flow
  7. 7. Did You Know Did you Know that a single helium tank can fill about 700 balloons .The reason that the tank can do that is because its under pressure
  8. 8. Properties of liquids  The particles move fast enough to overcome the attraction of some particles.  The particles slide past each other.
  9. 9. Gases  Gas-the state of Matter that has no definite shape or volume. The molecules in the gas move so quickly and stay far apart. The amount of space between the Gas can change.
  10. 10. STATES OF MATTER GAS  Particles of gases are very far apart and move freely.  Gases have an indefinite shape and an indefinite volume. Heat
  11. 11. Examples of gases  Helium  Oxygen  Nitrogen  Carbon dioxide  Argon
  12. 12. Did You Know  Did you Know that solids move slow, liquid move medium fast, and gases move constantly.
  13. 13. Changes in gases Most liquids and solids, gases expand when they are heated and contract when they are cooled. If both gas and liquid undergo the same temperature rise the gas expands about ten times more than the liquid.
  14. 14. EXPLOSIONS   Explosion occurs when a gas is made to expand very strongly and very quickly. It creates large forces that push on everything around.  The expansion is strong enough to break up rocks.
  15. 15. Properties of gases  Particles in a gas move quickly enough they can break away from their attraction for other particles.  The amount of empty space between gas particles can change.
  16. 16. Viscosity  All liquids have viscosity.  Viscosity  The – a liquid’s resistance to flow viscosity of a liquid depends on the attraction between it’s particles.
  17. 17. Example of viscosity  Ex: Water has a low viscosity, and that is why we have rivers. Honey has a high viscosity be cause it takes forever to flow. Water Honey
  18. 18. The two kinds of solids Amorphous Crystalline
  19. 19. PHASE CHANGES Description of Phase Change Solid to liquid Term for Phase Change Melting Liquid to Freezing solid Heat Movement During Phase Change Heat goes into the solid as it melts. Heat leaves the liquid as it freezes.
  20. 20. Introversion of three states of matter
  21. 21. Changes in Temperature Solid Condensati on Liquid Gas Evaporation
  22. 22. Changes in Solids  When a solid is heated, it expands and when it cools it contracts. E.G Railways: There are gaps between the end of the rails. In hot weather, the rail will expand and will buckle up.
  23. 23. Changes in Liquids  When liquids are heated, they expand much more than solids for a given temperature. E.G When water get hot, it expands and rises up the glass tube. While when the water is cool, the level of the water in tube falls
  24. 24. Strange fact about water!  When water cooled, it expands again when it’s temperature drops below 4 degree celcius.  After 4 degree celcius, it will start to expand until it reaches 0 degree celcius.
  25. 25. Changes in Gas o Gases expand when they are heated o Contract when they are cooled E.G. Hot air balloons: When the air in the balloon is heated, it expands and fills the balloon. The density of the air falls and it becomes less dense than the air around it. The surrounding area exerts an upthrust force which is greater than the weight on it.
  26. 26. The end Thank You For Paying Attention !!!
