A piece of paper is torn into small pieces is a physical change?
Answer (1)
Yes, tearing a piece of paper into small pieces is a physical change. This is because tearing changes only the paper's size and shape but does not alter its chemical composition. The paper remains chemically the same substance (cellulose), and no new substance is formed during the process. Unlike burning, which is a chemical change producing new substances, tearing is reversible in nature since the paper pieces can be taped or glued back together, showing no chemical change occurred.
