    Answer:

    1

    Explanation:

    chemical because first of all its simply not possible to create mass. second of all a physical; change is not done by creating a new substance, you can shred paper thats physical,  you burn paper, thats chemical. and finally a change of state is the three stages of matter, solid liquid and gas. none of these are changes that will always happen when there is a new substance is made.
