There is only a change in the state of matter and no chemical change has occurred and it is a reversible change. Whether it's a solid (ice) liquid (water) or a gas it's the same substance. Physical changes affect the state of an item, and a chemical change happens at a molecular level. On the other hand, chemical changes are a bit different.

Means it requires only a change of state the other hand, chemical changes are not chemically altered during process. The ions have now more space to move and interact with much more ions than in the solid phase. A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. It might be chemical because you add something different to the water an therefore its no longer just water. Boiling an egg causes both physical and chemical changes.
