is milk an example of chemical 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.
It is a chemical change because there is a chemical reaction occurring that is rotting the milk. An example of a physical change would be if the milk was evaporated or frozen.
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
Chocolate milk is a mixture called a colloid.
This is a chemical change.

Souring of milk is an example of a fermentation process. This occurs when bacteria in the milk convert lactose (milk sugar) into lactic acid, causing the milk to thicken and develop a tangy flavor. This process is commonly used to create products like yogurt and cheese.
This is a chemical change.
Yes, souring milk is an example of a chemical change. The breakdown of lactose by bacteria into lactic acid changes the composition of the milk, resulting in a new substance with different properties.
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
yes it is because a chemical change is way different than physical and a physical change is when it is still the same for example when you rip cut or crumble a pice of paper it is still the same !
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.
Cooking the eggs is a chemical change because the heat alters the molecular structure of the egg proteins, causing them to denature and coagulate. Adding milk to the eggs is a physical change because the milk remains unchanged in composition and simply mixes with the eggs.
No, it is a physical change.
