If the liquid water solidifies into ice, then it undergoes a physical change, not a chemical change. In a chemical change, you cannot alter the substance into its original state because it already has a new identity and composition. In the case of the freezing of water, the particles of the water did not change their composition. This is the reason why the ice can be returned to its original state. Once it melts due to heat, it becomes liquid water again.

In a chemical change, a new substance is formed.
