Answer

Brief Explanations:

Boiling water is a physical change as it involves a state - change from liquid to gas (vapor). The chemical composition of water ($H_2O$) remains the same. Gas formation during boiling is just a phase transition, not a chemical reaction that would transform water into a different substance. Temperature change during boiling is due to heat energy being used for the phase - change, not indicating a chemical transformation.

Answer:

physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved
