Answer 1

The change that is chemical is:

water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules

This process involves the breaking of chemical bonds in water to produce new substances (oxygen and hydrogen gas), which is a characteristic of a chemical change. The other processes listed are physical changes, as they do not result in the formation of new substances.
