Answer 1

Answer:

nature of change is physical change

formation of products is chemical change

change in chemical composition is chemical change

Explanation:

because if we take first case nature of change happens again and again as we know that physical change happens repeatedly so it is a physical change.according to second formation of products after formation of products the materials won't come back so it is chemical change.finally third case change in chemical composition leads to permanent change of material it won't come back so It is also a chemical.change
