Question

Could someone please help me with this question?

When an electric current is passed through water during the process of electrolysis, two gases are formed. One has a boiling point of -183°C and the other has a boiling point of -253°C. Has a physical change or chemical change occurs? Explain.

Answer 1

during electrolysis of H²0 we have Hydrogen nd oxygen gas evolution,
ideally the molecular structure of water has been broken down into Oxygen nd hydrogen
now a chemical change brings about such molecular dynamics, wherein a physical change only scratches the state of matter,
but since molecular configuration is involved, then it's a chemical change
