What type of change is chopping an apple considered?

Chopping an apple is considered a physical change because it involves altering the apple's size and shape without changing its chemical composition. During a physical change, the substance remains the same at the molecular level; its properties do not change, although its form does. For example, when you chop an apple, it retains its identity as an apple and still has the same taste, color, and nutritional value.

Physical changes can often be reversed, such as putting the chopped pieces back together, although in this case, the practical reversal may not be feasible. This contrasts with a chemical change, where substances transform into different substances with new chemical properties, which does not occur when simply chopping the apple. Understanding this distinction is key to recognizing the nature of physical changes in everyday life.
