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.

Chemical changes to matter affect the chemical properties. Examples of

chemical change include rusting, digesting, and rotting. These changes are not

reversible and involves the formation of new substance.

A. Ripping paper is a chemical change because the chemical structure of the

paper has changed.

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

C. Ripping paper is a chemical change because the change is not reversible.

D. Ripping paper is a physical change because the change only affects the size and shape, or its physical properties.

D. Ripping paper is a physical change because the change only affects the size and shape, or its physical properties.
