  • Phase: Physical changes can also cause substances to change phase, such as from solid to liquid (melting) or from liquid to gas (evaporation).
    • Myth: Physical changes always result in a loss of material properties.

    Physical changes occur when a substance undergoes a transformation without altering its chemical composition. This means that the material's properties, such as its shape, size, or phase, change, but its chemical makeup remains the same. Examples of physical changes include melting, freezing, sublimation, and condensation. These changes are often reversible, meaning that the substance can return to its original state.

  • Shape and size: Physical changes can cause materials to expand, contract, or change shape. For instance, when a metal is heated, it expands due to the increased kinetic energy of its atoms.
