Cutting paper is a physical change. This is because when you cut paper, you are altering its size and shape but not its chemical composition. The individual molecules and fibers that make up the paper remain unchanged; they still retain their original chemical properties.
In a physical change, the matter may change in form, appearance, or state, but its underlying chemical structure remains intact. For instance, whether the paper is whole, torn, or cut into smaller pieces, it is still made of the same cellulose fibers and retains its ability to be written on or printed on.
In contrast, a chemical change involves a transformation that affects the chemical structure of a substance, leading to the formation of new substances. Examples of chemical changes include burning paper, which produces ash and gases, or rusting iron, which leads to iron oxide.
Therefore, since cutting paper does not change its chemical identity or create new substances, it is classified as a physical change.
