How can you physically change a piece of paper?
In order to change the physical properties of an object, one must alter the 'format' of an object. An alteration of the physical properties is only a shift in the way an object can be described, not in the chemical composition of the product. In context a piece of paper could have its physical properties changed by being burned, being shredded, or by being submerged in water.
