* No new substance is formed: The sugar molecules are simply dispersing throughout the water. They are still sugar molecules.
* The change is reversible: You can easily recover the sugar by evaporating the water.
* Chemical bonds are not broken: The chemical structure of the sugar molecule remains intact.
In contrast, a chemical change would involve:
* Formation of new substances with different properties.
* Breaking and forming new chemical bonds.
* The change is typically irreversible.
Example of a chemical change: Burning sugar. This changes the sugar into ash and carbon dioxide, substances with entirely different properties.
