Which of the following is not an example of a chemical change? .

Well, I can tell you what a chemical change is and you can get your answer from there. A chemical change is when the very make up of the item is totally changed and can not be changed back. When one compound is converted into a totally new compound having different chemical properties. So... melting an ice cube would be physical and not chemical. Crumbling up a piece of paper would be physical becasue if you uncrumble it, it's still a piece of paper. But Burning paper would be considered chemical becasue now it's ash and you can't get that piece of paper back.  I hope this helps!! c:
