    2.1 Solids, Liquids & Gases

    Uploaded by

    John Michael Ditchon
    Solids, liquids and gases are the three states of matter. Solids have a fixed shape and volume, liquids have a fixed volume but can change shape, and gases can change both shape and volume. The properties of each state are different - solids are rigid, liquids are fluid, and gases are compressible. Matter is made up of tiny particles and changing temperature can cause it to change states.

    Keywords:
    • Substance – A matter that has specific composition and properties.

    • State – Distinct forms in which matter can exist.

    liquids, and gases?
    Do you know any examples?

    SOLID LIQUID GAS?
    States of matter
    • Matter is anything that has mass
    and volume (takes up space).
    • A particle is a small piece of
    matter.
    • All matter is made up of small
    particles and is in one of the
    three states; solid liquid or gas.
    • Properties = what the material is
    like and how it behaves.
    Solids
    • Have / keep the same shape and volume.
    • Cannot be compressed (squashed into a smaller space) or
    poured.
    Liquids
    • Have / keep the same volume, but the
    shape can change.
    • Cannot be squashed / compressed.
    • Can be poured. Mercury is the only liquid
    metal.

    Liquid particles are already close together, so they


    Liquids can be poured. cannot really be compressed.
    Gases
    • Volume and shape can change.
    • Can be compressed (squashed to fit in a smaller space).
    • Can expand to fill any closed container they are in.
    • Flow like a liquid.

    Gas particles can be compressed into


    Gases can flow.
    a smaller space.
    Properties of solid, liquid and gas

    Solid Liquid Gas


    • Fixed shape. • No fixed shape. • No fixed shape.
    • Fixed volume. • Fixed volume. • No fixed volume.
    • Difficult to squash. • Difficult to squash. • Easy to squash.
    • Do not flow easily. • Flow quite easily. • Flow easily.
    • Very dense. • Less dense than solid. • Not dense at all.
