2. Solid Solid-Thestate 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. 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. Solids 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. Liquid (cont.) There are Two properties in the liquid matter1.Surface Tension-the force that act on particles on the surface2.viscosity- A liquid resistance to flow 7. Did You Know Didyou 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. Properties of liquids Theparticles move fast enough to overcome the attraction of some particles. Theparticles slide past each other. 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. 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. Examples of gases HeliumOxygenNitrogenCarbon dioxideArgon 12. Did You Know Did you Know that solids move slow, liquid move medium fast, and gases move constantly. 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 aboutten times more than the liquid. 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. Properties of gases Particlesin a gas move quickly enough they can break away from their attraction for other particles. Theamount of empty space between gas particles can change. 16. Viscosity Allliquids have viscosity. Viscosity The a liquids resistance to flowviscosity of a liquid depends on the attraction between its particles. 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.WaterHoney 18. The two kinds of solidsAmorphousCrystalline 19. PHASE CHANGES Description of Phase ChangeSolid to liquidTerm for Phase ChangeMeltingLiquid to Freezing solidHeat Movement During Phase ChangeHeat goes into the solid as it melts. Heat leaves the liquid as it freezes. 20. Introversion of three states of matter 21. Changes in Temperature SolidCondensati on LiquidGas Evaporation 22. Changes in Solids When a solid is heated, it expands and when it cools it contracts.E.GRailways: There are gaps between the end of the rails. In hot weather, the rail will expand and will buckle up. 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. Strange fact about water! Whenwater cooled, it expands again when its temperature drops below 4 degree celcius. After 4 degree celcius, it will start to expand until it reaches 0 degree celcius. 25. Changes in Gas oGases expand when they are heatedoContract when they are cooledE.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. The endThank You For Paying Attention !!! 27.
