Spoiled milk is a chemical change because the proteins and fats in the milk break down into smaller molecules due to the action of bacteria, resulting in a change in composition and properties that cannot be reversed by physical means. This process is a decomposition reaction that involves the transformation of the milk's chemical makeup.

What two examples is the physical change and chemical change of milk?
An example of a physical change in milk is when you freeze it, changing its state from liquid to solid without altering its chemical composition. A chemical change in milk occurs when it sours, involving the breakdown of lactose by bacteria to form lactic acid, altering its chemical composition.
Is the spoiling of milk a chemical or physical change?
The spoiling of milk is a chemical change. This is because the bacteria in the milk breaks down the proteins and fats in the milk, leading to a change in its chemical composition and properties. It cannot be reversed by physical means such as cooling or filtering.
Is souring milk a physical or chemical change Why or why not?
Souring milk is a chemical change because it involves the breakdown of lactose (a sugar in milk) into lactic acid by bacteria present in the milk. This process changes the composition and properties of the milk, leading to the sour taste and thicker consistency associated with spoiled milk.
When milk turns sour is it a chemical or physical change?
