## Step 1A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. This means that the substance's chemical composition remains the same, even though its physical appearance may change.## Step 2Looking at the options, we can see that "cutting a substance into four pieces" is a physical change. This is because the substance's chemical composition remains the same, even though its physical appearance changes.## Step 3On the other hand, "burning a substance into ash and smoke", "reacting a substance chemically to form a new substance", and "combining a substance with water to make rust" are all examples of chemical changes. This is because they result in new substances with different chemical compositions.
