When milk turns sour for example in a warm room it is a chemical change. If it was a physical change you would be able to undo the souring of milk.
Explanation:
Physical changes can be reversed, like melting and freezing something such as water into an ice cube, then back to water again, or a candle wax melting, then you can freeze it back again.
A chemical change cannot be undone, such as mixing ingredients for a cake and baking it, once it has been baked, you cannot take out the ingredients like the eggs the flour etc. , or breaking an egg.
