    Study Notes

    Characteristics of Matter

    Solids

    • Have definite size, shape, hardness, texture, and color.
    • Exhibit higher density compared to liquids and gases, meaning mass per unit volume is greater.
    • Physical properties can be easily observed and identified through practical experiments.

    Liquids

    • Contain fewer molecules than solids, leading to increased molecular distance.
    • Molecules are held together by sufficient attractive forces to maintain a constant volume.
    • Volume stays consistent, but shape is not fixed, adapting to the container.

    Gases

    • Lack a fixed shape and occupy the entire volume of their container.
    • Extremely weak intermolecular forces result in negligible attraction between gas molecules.
    • Gases exert pressure uniformly in all directions on the walls of the container.

    Conversion of States of Matter

    • Melting occurs when solid ice is heated, converting it to liquid.
    • Vaporization is the process where liquid turns into gas upon further heating.
    • Gas can be cooled and converted back to liquid (liquefaction), and further cooling transforms it into solid (solidification).
