Answer:
1)A moth bursting out of a cocoon is neither a chemical or physical change, it's a biological change. If I had to chose it would be a physical change though. Not to sure...
2)Playing with slime is a physical change.
Explanation:
1)The reason why I would chose physical change is because the moth is changing it's physical state more than it's chemical composition, but you should say both if that's an option.
2)A physical change is when the temperature, shape, or state of matter changes. A chemical change occurs when the actual substance changes. An example of this is a chemical reaction. Because the slime is changing shape and not substances, I would say that it's obviously a physical change.
Hope this helps, sorry that I'm not too sure about the 1st question.
