    Study Notes

    States of Matter

    • Solids are compact particles that can't be pushed closer together.
    • Liquids are particles that have space between them and move freely.
    • Gases are widely spaced particles that can be compressed.
    • Plasma is a gaseous state containing electrically charged particles.

    Physical and Chemical Properties

    • Physical properties don't change a substance's chemical composition.
    • Examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
    • Physical changes alter state or properties without changing the chemical identity.
    • Examples of physical changes include melting wax, dissolving sugar in coffee, and steam condensing into water.
    • Chemical properties describe a substance's ability to change into another substance.
    • Examples of chemical properties include flammability, toxicity, acidity, and reactivity.
    • Chemical changes result in new substances with different properties.
    • Examples of chemical changes include rust formation, nitroglycerin explosion, and combustion.

    Extensive and Intensive Properties

    • An extensive property depends on the amount of matter present.
    • Examples of extensive properties are mass and volume.
    • An intensive property is independent of the amount of matter present.
    • Examples of intensive properties include temperature and density.

    Classifying Matter

    • A pure substance has a constant composition.
    • Examples of pure substances include elements (Fe, Ag, Au, S, O, Cu) and compounds (mercury(II) oxide).
    • A mixture is composed of two or more substances in variable proportions.
    • Heterogeneous mixtures have non-uniform composition (examples: salad dressing, sand and water).
    • Homogeneous mixtures (solutions) have uniform composition (example: sports drink).

    Separation Methods

    • Filtration separates solids from liquids using a filter.
    • Distillation separates liquids based on boiling point differences.
    • Magnetic separation uses magnets to separate magnetic solids from non-magnetic ones.
    • Decantation separates liquids based on density by carefully pouring the less dense liquid.
    • Sublimation separates a volatile solid from a non-volatile solid by directly converting the volatile solid to gas.
    • Chromatography separates components based on their ability to adsorb to a stationary phase.
    • Physical manipulation involves physically separating components in a mixture.
