Likewise, water changes into steam when boiling reveals physical change activity. physical change . Answer to The boiling of water is aa. Boiling water is a physical change, as it rearranges molecules but does not affect the internal structures. A physical property is a property that can be observed without changing the physical nature or composition of a substance. The ions display different properties from the original compound.
