Mrs. Clark has demonstrated a physical change involving change of shape and size of matter. When the piece of paper is cut into smaller pieces, its mass remains the same (20 g), which indicates that the change is physical rather than chemical.
Mrs. Clark decides to do a demonstration for her class with a piece of notebook paper. Using a balance, Mrs. Clark discovers that the mass of the paper is 20 g.
