Yes it is a physical change. The only other option is chemical change and the metal didnt change its chemical make up, it only changed its shape, and shape is the only thing that did change.
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
If the sheet is turning into a pillowcase, it would be a physical change. The sheet is not changing anything but its shape to become a pillowcase, and it most likely can be reversed to turn back into a sheet.
Sheet metal can be made of different materials. It is called sheet metal because of its shape which is thin and flat.
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
Sheet metal brakes are not especially hard to install. Most sheet metal brake purchases will include directions on how to safely and properly install them.
Physical one.
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.

The torn sheet has undergone a physical change, the burned sheet has undergone a chemical change, and the crumpled sheet has undergone a physical change.
It is a physical change because it is still a sheet of paper.
I think you are referring to a method of locating a nut in a piece of sheet metal. A rivet head nut is a nut with has a small projection not much thicker than the sheet metal to which you intend to fit it. This projection fits through a pre made hole in the sheet metal, and the small projection is peened over (deformed by hammering) to fix the nut to the sheet.
It is a physical change because it has not changed its chemical composition.

No, this is a physical change as you still have paper, nothing new is produced.
These are chemical reactions (changes).
It depends on what you are attaching to the sheet metal. Are you screwing together two layers of sheet metal? Or are you attaching a wooden block, for example, to the sheet metal? metal frame to the sheet metal
