Physical changes to matter affect the physical properties like size, shape, and physical state. Examples of physical changes include tearing, freezing, and melting. These changes are usually reversible (can be undone).

Chemical changes to matter affect the chemical properties. Examples of chemical change include rusting, digesting, and rotting. These changes are not reversible (permanent) and involves the formation of new substance

Which statement is true?

• Ripping paper is a chemical change because the chemical structure is changed.

• Ripping paper is a physical change because a new substance forms.

• Ripping Paper is a chemical change because the change is not reversible.

• Ripping Paper is a physical change because it only affects its size and shape.
