A chemical change involves a change in a substance's chemical make-up or conversion to a different substance. A physical change is one that involves changes in a substance's physical makeup that is not brought about by a chemical change, such as sugar dissolving in water. Therefore, mixing milk and chocolate syrup is not a chemical change. Now, if for some reason the syrup had a strong enough acid in it, and mixing the two made the milk curdle or solidify, then yes, it would be a chemical change.
Is cornflour and water a physical change?
Adding cornflour to water is a physical change.

If this became CH for some reason, it would be a change in the formula structure, a change yuo cannnot see.
