    Study Notes

    Properties of Matter

    • Properties of matter can be physical or chemical
    • Physical properties can be observed or measured without changing the substance's chemical composition
      • Examples: mass, density, color, volume
    • Chemical properties reflect how a substance will react with other substances
      • Examples: reactivity, flammability, pH

    Physical Properties

    • Solubility describes the ability of a substance to dissolve in a solvent
      • Sugar is highly soluble in water, while sand is practically insoluble
    • Density is a measure of how much mass is contained in a given volume
      • Iron has a higher density than water, which is why it sinks
    • Hardness is a measure of a substance's resistance to scratching or indentation
      • Diamonds are known for their hardness
    • Volatility describes how easily a substance evaporates at a given temperature
      • Highly volatile substances evaporate quickly, while less volatile substances evaporate slowly
    • Ductility is the ability of a substance to be drawn into a wire without breaking
      • Many metals are ductile
    • Malleability is the ability of a substance to be hammered or rolled into thin sheets without breaking
      • Metals are commonly malleable
    • Viscosity is a measure of a fluid's resistance to flow
      • Honey is more viscous than water
    • Heat conductivity is a measure of a substance's ability to transfer heat energy
      • Metals are good heat conductors
    • Electrical conductivity is a measure of a substance's ability to conduct electricity
      • Silver, gold, and copper are excellent electrical conductors

    Chemical Properties

    • Flammability is the ability of a substance to catch fire and burn
    • Reactivity describes the tendency of a substance to undergo chemical reactions
      • Sodium reacts violently with water

    Intensive vs Extensive Properties

    • Intensive properties depend only on the type of matter, not the amount
      • Examples: density, color, melting point, electrical conductivity
    • Extensive properties depend on the amount of matter present
      • Examples: mass, volume, length
