Alcohol added to water- what type of change is it?

Question

I need a source showing that diluting alcohol with water is not a chemical change, this for a test question with a block headed chem teacher my offspring is suffering this year.  Or to prove me wrong, so I can aplogize to the putz.  (It isn't even a physical change, the alcohol continues in the same liquid state).  An Internet source would be better.

It is a physical change. No molequles are changed. Physical properties are changed, like alcohal becomes diluted.

im pretty sure that its a physical change, because after you add alcohol to water, it can be spearated into components using a physical means (maybe electrolysis or distillization). Anything thats a chemical change has to do with a change in color, the presence of bubbles, smell, parcipitation or temperature change. adding alcohol does none of these (but maybe there may be an endothermic energy change)
