The change that is chemical is:
**water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules.**
This process involves breaking the chemical bonds in water (H2O) to produce two different substances: hydrogen (H2) and oxygen (O2), which is a chemical change. The other processes mentioned are physical changes, where the state of the substance changes but its chemical composition remains the same.
