Yes this is a physical change because they are melting it and then it's being changed by the heat of the torch but heat is a physical change.
Physical Change, the metal has the same chemical structure and only the shape of the bar has changed
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
no it is a chemical change
Bending a paper clip is a physical change because the composition and structure of the paper clip remain the same. No new substances are formed during this process.

Yes it is most definitely!
Bending a metal is a physical change because it does not alter the chemical composition of the metal. The change is reversible, meaning the metal can be straightened back to its original shape without altering its properties.
