Explanation:

A physical change alters the form or state of matter without changing its chemical composition. When an icicle melts, it changes from a solid (ice) to a liquid (water). The substance is still H₂O throughout the process; no new substances are formed. In a chemical change, new substances with different chemical properties are created through chemical reactions. Since melting an icicle only involves a change in state (solid - liquid) and not a change in chemical makeup, it is a physical change.

Answer:

An icicle melting is a physical change. The basis is that no new substances are formed; it is just a change from solid ice to liquid water with the same chemical composition (H₂O).
