What happens to substances or materials that undergo physical and chemical changes?

That depends on which change.
Physical changes may result in a change in appearance, but never a change in composition. Ripping, folding, melting, boiling, dissolving, and crumpling are examples of physical changes. After all of these, the substance is still made of the same atoms/elements.
A chemical change will change both the appearance and composition of the matter. Examples of this are burning and reacting with acid. After the change, the substance both looks different and has a different makeup.

What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
