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.
Dissolving salt in water and making ice cubes
Chemists are primarily interested in studying physical changes, which involve a change in appearance or state of matter without a change in composition, and chemical changes, which involve a change in the chemical composition of a substance.
Melting ice is an example of a physical change. The solid ice changes to liquid water without altering its chemical composition.
physical change. When sugar is heated, it changes from a solid to a liquid state without changing its chemical composition.
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
because it changes its chemical composition.
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.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase change.

It is a physical change because the chemical composition of the substance does not change.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
