    Study Notes

    States of Matter

    • Matter can be classified into three states: solids, liquids, and gases.
    • Solids have a fixed shape and volume, cannot be compressed, and cannot be poured.
    • Liquids take the shape of their container, can be poured, cannot be compressed, and have a fixed volume.
    • Gases flow like liquids, fill any container, are easily compressed, and have variable volume.

    Particle Theory

    • The particle theory explains how particles are arranged differently in solids, liquids, and gases.
    • Solids have particles in fixed positions, tightly packed, and held together strongly.
    • Liquids have particles touching, held together weakly, allowing movement past each other.
    • Gases have particles far apart, no attractive forces between them, allowing free movement and expansion.

    Changes of State

    • Matter can change state by adding or removing heat.
    • Heating can cause a solid to melt into a liquid or a liquid to vaporize into a gas.
    • Cooling can cause a gas to condense into a liquid or a liquid to freeze into a solid.

    Modeling Particles

    • Particle theory can be modeled by arranging people in different ways to represent solids, liquids, and gases.
    • Solid models should have individuals in a fixed pattern, close together, and unable to move.
    • Liquid models should have individuals touching but able to move past each other.
    • Gas models should have individuals spread out, with no contact, and free to move in any direction.
