  • Physical Change
    type of change in which the substance's appearance, shape, or form is altered, but its chemical composition remains the same
  • Physical Change

    • Changes of state
    • Dissolving
  • Chemical Change
    happens when the substances involved completely transform into different substances with new properties. Original stuff has chemically reacted to form something totally new.
  • Chemical Change

    • Combustion
    • Corrosion
  • Clues that a Chemical Change has occurred
    • Heat or light is given off
    • A solid material called a precipitate, is formed
    • Bubbles of gas are formed
    • New odour or the change is irreversible
    • A new colour appears
  • BEPIC

    • Bubbles
    • Energy (heat/light)
    • Precipitate
    • Irreversible (mostly)
    • Colour Change
  • Physical Properties

    • State: solid, liquid, gas
    • Colour: clear, pink, blue, green, black, white, etc.
    • Odour: sweet, pungent, odourless, etc.
    • Clarity: Transparent, Translucent, Opaque
    • Luster: shiny or no?
    • Texture: smooth, bumpy, waxy, fine, coarse, granular
  • Chemical Properties
    1. Reactivity: How likely it is to mix and react with other stuff.
    2. Flammability: If it can catch fire easily.
    3. Toxicity: How harmful it is to living things.
    4. Corrosiveness: If it can eat away or damage other things it touches.
  • Chemical change

    Involves changes in the compound creation or bonds that allow it to form a new substance
  • Physical changes

    • Freezing water
    • Solutions like Kool Aid
    • Salad Dressing on salad
    • Wax hardening
    • Sugar dissolving in tea
  • Chemical changes

    • Molding bread/fruit
    • Baking cookies
    • Sulfur burning
    • Metal rusting
    • Tarnish (losing luster due to exposure of air or moisture)
  • Change from gas to solid
    ER

    1. Stability: How well it keeps its form without changing.
    2. Combustibility: How easily it burns.
    3. pH: How acidic or basic it is.
    1. Oxidation state: Whether it's gained or lost something in a reaction.
    2. Solubility: If it dissolves in water or other liquids.
    3. Sensitivity to light or heat: How it reacts when exposed to light or heat.
