⚫electrolytic decomposition of water is a reaction involving change of state.

⚫in this , water is electrolyed , so that it dissociates into two parts :- hydrogen and oxygen.

⚫when water changes to gaseous state , it means vaporization takes place.

⚫this actually involves change of state from liquid to gaseous form.

HOPE IT HELPS
