Hammering hot iron into a sheet chemical or physical change?
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
Is wadding a sheet of paper a chemical change?
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
What is a very thin sheet of metal called?

A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is hammering metal into a flat sheet physical change?
Yes, hammering metal into a flat sheet is a physical change. The metallic bonds between atoms remain intact as the metal is reshaped, just the arrangement of atoms changes.
Is hammering metal into a flat sheet physical or chemical 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.

When a sheet of paper is cut in half is that a physical change?
Yes, cutting a sheet of paper in half is a physical change because the paper's properties, such as its shape and size, are altered, but its chemical composition remains the same.
Is bleaching a sheet and a pillowcase phisycal or chemical change?
