    A physical change does not produce a new substance. change in state or phrase. (melting, freezing, vaporization, condensation, sublimation) are physical changes. example of physical changes include crushing a can, melting an ice cube, and breaking a bottle. a chemical Change makes a substance that wasn't there before.

    Answer: Option (A) is the correct answer.

    Explanation:

    Physical change is defined as a change that does not bring any changes in the chemical properties of a substance.

    For example, solubility, density, volume etc are all physical changes.

    When sugar dissolves in water then it is a physical change.

    Whereas color change may not necessarily shows a physical change because a chemical change can also lead to color change of a solution or substance.

    For example, rusting of iron is a chemical reaction in which color change also occurs.

    Hence, we can conclude that a solid dissolves when added to a liquid is most clearly an example of a physical change.
