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 is churning a chemical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
What drinks can you make with sweet and sour mix?
Sweet and sour mix can be used to make cocktails such as whiskey sours, margaritas, and amaretto sours. It is a versatile ingredient that adds a balanced sweet and tangy flavor to many drinks.
What will be a good title of recycle?

What is 1 food that bacteria are used to make?
Well, the bacteria change lactose into lastic acid, and the Lactic Acid preserves and adds flavor to the food. That's the answer I hope this work Anne
When milk sours does it become a physical change?
No it is a chemical change because you change it back to normal.
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.
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.
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.
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 sours a physical or chemical change?
chemical change
What type of property is observed when milk sours?
Milk souring is a chemical property, as it involves a chemical change in the milk caused by the action of bacteria that convert lactose into lactic acid. This change alters the taste and texture of the milk.
When milk sours it undergoes a chemical change because?
yes because it is a different substance than before :)
Is milk souring a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
Why is churning a chemical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Is turning milk into ice cream a chemical change or a physical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
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.
