A physical change occurs.
The changes produced by electrolysis are chemical.
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
As matter changes from solid to liquid (in other words when solid matter melts) the temperature remains constant. After all the solid has melted, the temperature of the matter may begin to rise again if the environment is warmer than the melting point of the solid.

gas to a liquid
no physical change does not change matter
no physical change does not change matter

A compound that can be separated by electrolysis must be in the LIQUID state of matter.

something magical.
You are adding heat/energy. It is melting.
oxidation
it occurs as compounds, reacted with other elements, and can be separated through the process of electrolysis
Water is dissociated in hydrogen and oxygen.
