Alcohol added to water- what type of change is it?
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.
I know it is not a chemical change but I need some sort of source, a reference. Also I believe it is not a physical change either, the liquid alcohol remains liquid alcohol (with some evaporation unless confined).

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)
