An example of a physical change is the melting of ice into water. This process alters the state of matter from solid to liquid without changing its chemical composition. Other examples include breaking a glass, dissolving sugar in water, and freezing juice to make ice pops. Understanding physical changes helps distinguish them from chemical changes, where the substance's chemical structure is modified.
