The group of students is incorrect. Boiling water is NOT a chemical change. The group incorrectly identified it as a chemical change because the water changed to steam and bubbles.

Boiling water is a physical change to steam and bubbles but it is still water. The steam puts itself into the air as evaporation. The opposite of evaporation is condensation, when water vapor condenses back into tiny droplets of water.

A chemical change is when something changes and becomes a new substance or property, like burning wood.

A physical change is when the appearance or form of the substance changes but the kind of substance doesn’t, just like the boiling water.
