  • *Review how molecules move differently in solids, liquids, and gases (note solid particles still moving)
  • *A: temperature rises, or if at specific point, change of state occursPhysical property: state physical change: change of state
  • Physical properties kinetic theory me3

    1. 1. Physical properties and kinetic theoryKinetic theory or matter – States all particles of matter are constantly in motion.State (Phase) of matter:Q. What are two things that can happen when energy is added to asubstance?
    2. 2. A: Change of temperature or state
    3. 3. Volume(Space Occupied)Ex. Even concrete needs to expand due to heat. Expansion joints are created inbridges and roads to allow for this natural adjustment.Q: What are two ways tomeasure volume?
    4. 4. Measuring Volume• V=lwh• Graduated Cylinder• Fluid Displacement
    5. 5. Mass(Amount of matter an object or substancecontains)Q. What tool might be used to find the mass ofan object?
    6. 6. Balance
    7. 7. DensityDensity – Amount of matter present in a certain volume. Density = Mass/volumeQ: How does this relate to kinetic theory?
    8. 8. Physical properties cont.ViscosityTendency of a substance to resist flowResults in slower or faster movement of substance particles. Low energy = low heat = thickness and slow flow. Ex. (honey from refrigerator) High energy= high heat = thinner and faster flow. Ex. (honey from microwave)KkSubstances get thicker as temperatures (energy amount) lower.Substances get thinner as temperatures rise.
    9. 9. How does viscosity relate to kinetic theory?• Draw and label how the molecules of a viscous substance might be different from a non- viscous substance.
    10. 10. Solubility(How a substance dissolves in a given volume of liquid.)Ex. Salt or sugar dissolves much better than dirt in a given volume ofliquidWhat happens to mud or dirt when It’s put in water? Dirt in solvent(different properties than sugar)
    11. 11. NEW VOCABULARY!!• Dissolving - disappearing visually in a solvent• Solute – substance (usually a solid) being dissolved in a liquid.• Solvent – substance (usually a liquid) doing the dissolving.
    12. 12. Think back to lab…Temperature most definitely determines howquickly something can dissolve!!Sugar in hot coffee vs. cold coffee Cold Solvent Hot Solvent
    13. 13. MalleabilityAbility of a substance (usually metals) to be formed into different shapes withoutbreaking.- Metals have many uses in the world because of this property.- Can you name a few?
    14. 14. Physical ChangeAny change that is made to a substances physical properties - observed without changing the identity (internal makeup) of asubstance. - Always ask yourself if the identity of the substance is the sameor not following a change. What happens to water as it goes from liquid to a solid? Is this a physical change or not ( a chemical change)?
