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.
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.
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 souring a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
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.
If you have a bowl of milk and cheerios would it become a chemical or physical change?
physical 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
When milk sours it undergoes a chemical change because?
yes because it is a different substance than before :)
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.
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.
