what is an example of a physical change?\no having less ash than the paper that was burned to form it\no ice forming and then melting back into water\no rust having a different identity than the iron it forms on\no the irreversible reaction of vinegar and baking soda

Answer

Answer:

B. ice forming and then melting back into water

Brief Explanations:

A physical change alters a substance's form without changing its chemical composition. Ice - water transformation is a phase change (solid - liquid) which is physical. Burning paper is a chemical change as new substances are formed. Rusting of iron is a chemical reaction forming a new compound. Vinegar - baking soda reaction is a chemical reaction producing new substances.
