It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Physical. The metal wire is still a metal wire after the change.

yes because the wire doesn't change its characteristics
Bending a copper wire is a physical change because the copper itself does not undergo a chemical reaction. The arrangement of copper atoms simply changes temporarily when the wire is bent, but the properties of copper remain the same.
When metal is drawn out into a wire, it is a physical change. This process involves altering the shape and form of the metal without changing its chemical composition. The metal retains its properties, such as conductivity and malleability, even after being transformed into wire.
a flexible piece of metal
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
Physical. The metal is still metal, even though now it's wire-shaped.
yes it can it the bow bending not the string stretching
Yes. The wire and the block are still composed of the same material - only the shape has changed.
It is a physical property. Malleability is a physical property in lots of metals (including copper). It is not a characteristic property, because it is not unique to copper. (Other metals share the same property).
A chemical change is when something cannot be reversed and often a precipitate (solid) is formed. While a physical change can be reversed e.g bending a piece of wire.
