How is sour milk a chemical change?
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.
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.
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.
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 chemical change does heating of coconut milk til its brown syrup?
Yes, heating coconut milk until it turns into brown syrup is a chemical change. The heat causes the milk's proteins and sugars to undergo a series of complex reactions that lead to a change in its color, consistency, and flavor, creating a new substance with different chemical properties.
When milk turns sour this is a physical change because a change in odor does not indicate a chemical change?
Actually, when milk turns sour, it is primarily a chemical change rather than a physical change. This occurs due to the fermentation process, where bacteria convert lactose (milk sugar) into lactic acid, resulting in a change in odor, taste, and texture. The formation of new substances, such as lactic acid, signifies a chemical change, as opposed to a mere alteration of physical properties.
