When milk turns sour this is a physical change because a change in odor does not indicate a chemical change?
Actually, when milk turns sour, it is primarily a chemical change rather than a physical change. This occurs due to the fermentation process, where bacteria convert lactose (milk sugar) into lactic acid, resulting in a change in odor, taste, and texture. The formation of new substances, such as lactic acid, signifies a chemical change, as opposed to a mere alteration of physical properties.
