Answer 2

Answer:

See below

Explanation:

If a piece of wire is coiled to form a spring, it is a physical change. This is because there is no change in it's bonds rather there is a change in its shape and figure. Also, Physical change is reversible such that the coiled piece of wire can be changed back to a straight piece of wire. But, A chemical change is irreversible.

So, This is a physical change.
