Is mixing milk and lemon juice chemical or physical change?
Mixing milk and lemon juice results in a chemical change. The acidity of lemon juice causes the proteins in milk to denature and coagulate, leading to curdling. This process alters the composition of the milk, producing new substances like curds and whey. Thus, the change is not reversible, indicating a chemical transformation.
Is a bottle of milk that sours a physical or chemical change?
This 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.
Is mixing milk and vinegar a physical or chemical change?

Is chocolate milk an example of a chemical change physical change or a mixture?
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.
Is Curdling of milk a chemical change?
when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.
Is vinegar in milk a physical or chemical change?
When vinegar is added to milk, it causes a chemical change. The acetic acid in vinegar reacts with the proteins in milk, leading to curdling and the formation of solid curds and liquid whey. This process alters the composition of the milk, indicating a chemical transformation rather than just a physical change.
Is curdling of milk physical or chemical?
The curdling of milk is a chemical process. It occurs when proteins in the milk, such as casein, interact with an acid (like lemon juice or vinegar), causing the proteins to denature and clump together, forming curds. This process is irreversible and results in a change in the composition of the milk.
Is mixing milk and lemon juice chemical or physical change?
Mixing milk and lemon juice results in a chemical change. The acidity of lemon juice causes the proteins in milk to denature and coagulate, leading to curdling. This process alters the composition of the milk, producing new substances like curds and whey. Thus, the change is not reversible, indicating a chemical transformation.
Is curdling of milk a reversible or irreversible change?
Yes, but it is so hard as not to be worth it.
Is boiling milk a physical change or chemical?
Boiling milk is a physical change because it does not alter the chemical composition of the milk. The heat causes the milk to change from a liquid to a gas without changing its molecular structure.
Is a bottle of milk that sours a physical or chemical change?
This is a chemical change.
Are drops of cold milk added to hot coffee a chemical or physical change?
Adding cold milk to hot coffee is a physical change because the milk and coffee retain their original chemical properties after mixing. The change in temperature is a physical property of the substances.

It is never milk again. It will just be churds and whey it will never change back. It changes the substances identity.
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.
Is milk sours a example of physical change?
