    Study Notes

    States of Matter

    • Four main states of matter:
      • Solid
      • Liquid
      • Gas
      • Plasma (high-energy state, not commonly encountered in everyday life)
    • Characteristics of each state:
      • Solid: fixed shape and volume, particles closely packed
      • Liquid: takes shape of container, particles close but able to move past each other
      • Gas: takes shape and volume of container, particles widely spaced and freely moving

    Types of Matter

    • Elements: simplest form of matter, cannot be broken down into simpler substances (e.g. hydrogen, oxygen, carbon)
    • Compounds: composed of two or more different elements, chemically bonded together (e.g. water, salt, sugar)
    • Mixtures: combination of two or more substances, not chemically bonded (e.g. air, soil, blood)

    Changes of State

    • Phase transitions:
      • Melting: solid to liquid
      • Freezing: liquid to solid
      • Evaporation: liquid to gas
      • Condensation: gas to liquid
      • Sublimation: solid to gas (e.g. dry ice)
      • Deposition: gas to solid (e.g. frost)
    • Factors affecting changes of state:
      • Temperature
      • Pressure
      • Surface area

    Chemical Properties

    • Reactivity: ability of a substance to undergo a chemical reaction
    • Flammability: ability of a substance to catch fire
    • Corrosivity: ability of a substance to wear away or destroy other materials
    • Toxicity: ability of a substance to cause harm or poison living organisms

    Physical Properties

    • Color
    • Odor
    • Texture
    • Density
    • Solubility
    • Boiling and melting points
    • Viscosity
    • Conductivity (heat, electricity, or sound)
