Is milk souring a chemical or physical change or both?
Well just to start off nothing can ever be a physical and chemical change it has to be one or the other.. and the best way to know which one it is is a physical change doesnt change the substance and a chemical change will change the substance into something else. So milk going sour would be chemical because it isnt regular milk anymore its sour milk. but if it was something like evaporating water then it would be physical because its still water its just in the gas state. -Hope that helps(:
