    A physical change is a change in the physical properties (e.g., shape, state, or size) of a substance without altering its chemical composition.
    Sublimation is the process where a substance changes directly from a solid to a gas (or vice versa) without passing through the liquid phase.
    Example: Dry ice sublimates directly into gas.
