It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.

Is souring milk a physical or chemical change Why or why not?

It's a chemical change. The smell is the giveaway; a smell that wasn't there before is often an indicator of a chemical change. Also, the rate at which the milk sours can be changed by heat. For example, milk in the refrigerator is actually undergoing this souring reaction at all times, but the lower temperature inside the refrigerator slows it down so that it takes many days. But if you leave it outside the refrigerator, it will sour much more quickly - in a matter of hours. An increase in heat, therefore, quickens the reaction rate. This would not be the case in a physical change.

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(:
