    Study Notes

    Physical Properties

    • Definition: Characteristics of matter that can be observed or measured without changing its identity.
    • Size-dependent: These properties depend on the amount of matter in a sample. Examples include mass, weight, and volume.
    • Size-independent: These properties do not depend on the amount of matter in a sample. Examples include color, luster, state of matter, melting point, boiling point, solubility, conductivity, density, malleability, hardness, and viscosity.

    Chemical Properties

    • Definition: Characteristics of matter that can only be observed as it changes to a different type of matter.
    • Examples: Flammability, reactivity with oxygen, reactivity with sulfur, acidity.
    • Observation: Observing chemical properties requires a change in the substance, e.g., burning something or reacting it with something else.

    Physical Changes

    • Definition: A change in the form or appearance of a substance without forming a new substance.
    • Characteristics: Reversible
    • Examples: Melting ice, dissolving sugar in water, tearing fabric.

    Chemical Changes

    • Definition: A change in a substance that produces one or more new substances with different properties.
    • Characteristics: Irreversible.
    • Examples: Burning wood, rusting iron, baking bread.
    • Indications of Chemical Change: Color change, gas production (bubbles, smoke, etc.), change in odor, emission of energy (heat, light, sound).
