Milk undergoes a chemical change during processes like fermentation, where bacteria convert lactose into lactic acid, resulting in souring. Additionally, when milk is heated, proteins like casein denature and coagulate, forming curds and altering the milk's composition. These changes are not reversible, indicating a transformation at the molecular level, which is characteristic of chemical changes.

Is curdling of milk is physical change or chemical change?
Milk curdling is a chemical change.
Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.

Why Milk souring is a physical change?
When milk sours, it undergoes a chemical change rather than a physical change. The bacteria in the milk ferment the lactose sugar into lactic acid, changing the chemical composition of the milk. This process cannot be reversed by physical means, distinguishing it as a chemical change.
When milk sours it undergoes a chemical change because?
yes because it is a different substance than before :)
Is curdling of milk is physical change or chemical change?
Milk curdling is a chemical change.
Can you consider a chemical change souring a milk?
Yes, when milk sours, it undergoes a chemical change due to the actions of bacteria that ferment the lactose in the milk, producing lactic acid. This change in pH causes the milk to coagulate and develop a sour taste and smell.
Is milk sours a physical or chemical change?

What is a physical change Milk becomes sour an iron nail rusts?
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
Is milk turning sour a physical or chemical change?
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
