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. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
Physical or chemical hammering gold into a thin foil?
Hammering gold into a thin foil is a physical process. It involves physically breaking down the gold and flattening it into a thin sheet without any change in its chemical composition. This is in contrast to a chemical process, which would involve altering the gold's chemical structure or composition to create a thin foil.
Is bleaching a sheet and a pillowcase phisycal or chemical change?
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.
Is crumpling a sheet a paper a physical or chemical change?
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
Is steel the same as sheet metal?
No, steel is a specific type of metal alloy that contains iron and carbon, while sheet metal is a form of metal that is produced as thin, flat pieces. Steel can be made into sheet metal, but not all sheet metal is made of steel.
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.

What are examples of chemical reaction?
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.
Give three examples of revsersible physical changes?
1> Melting of ice 2> Making of cloud 3> Hammering a metal into sheet

What happens when athin sheet of metal is hammered is again and again?
When a thin sheet of metal is hammered again and again, it becomes thinner, longer, and wider. The repeated hammering causes the metal's atoms to spread out and align in the direction of the force, making the metal more malleable and shaping it into the desired form. This process of shaping metal through repeated hammering is known as metalworking or forging.
What does mean recess head rivet nut?
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.
A sheet of paper is torn in half Another sheet is burned A third sheet of paper is crumpled into a ball What kind of change has each sheet of paper undergone?
Well, isn't that interesting! The first sheet of paper underwent a physical change when it was torn in half. The second sheet experienced a chemical change when it was burned. And the third sheet went through a physical change when it was crumpled into a ball. Each sheet transformed in its own unique way, just like how every brushstroke creates a beautiful painting.
Is cutting a paper physical or chemical change?
It is a physical change because it is still a sheet of paper.
Ability of a metal to be made into a sheet because of its bonding?
The ability of a metal to be made into a sheet is due to its metallic bonding, which involves the sharing of electrons among metal atoms. This bonding characteristic allows metals to be easily deformed without breaking, making them ideal for processes like rolling or hammering to form sheets.
What is a physical change such as bending folding or tearing?
A physical change is a change that affects the form of a substance without altering its chemical composition. Examples include bending a metal sheet, folding a piece of paper, or tearing a piece of fabric.
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.
