It's a physical change because it alters the physical state (size, amount, shape, etc) of the object. It is still chemically identical before and after the change, however the physical characteristics have been changed.
A chemical change is one that alters the chemical composition of the item, for example the rust on a piece of iron is a chemical change because the new chemical composition is iron-oxide as opposed to iron.

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,
What changes occur to raw materials during the paper making process?
Papermaking is a series of physical and chemical changes. The physical and chemical changes will depends on raw material used and grade of paper manufactured. For a typical north American paper mill which uses wood for making copying paper, following changes will take place.

How is shredding paper a physical change?
Shredding paper involves changing the physical appearance and form of the paper without altering its chemical composition. The paper is simply being torn into smaller pieces, making it a physical change rather than a chemical one.
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.
What are two chemical properties of a sheet of paper?
A sheet of paper is generally flammable, due to its high cellulose content. Paper is also capable of undergoing a chemical reaction with acids, such as becoming discolored or deteriorating when exposed to acidic substances.
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 cutting a paper physical or chemical change?
It is a physical change because it is still a sheet of paper.
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.
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.
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.
What kind of change has each sheet of paper undergone?
Depending on the experiment, there will be a series of physical and chemical changes.
Why is it hard to crumple a full sheet of paper with one hand?
It may or may not be hard, depending on your hand size and strength. Since the paper is bigger than most hands, some people have difficulties crumpling them. I just half crumple a sheet and throw it away.
A physical change differs from a chemical change in that waste products are formed through chemical changes?
In a physical change, the substance retains its chemical composition, but its physical state may change, such as melting or freezing. In a chemical change, the substance undergoes a change in its chemical composition, resulting in the formation of new substances.

How can you make a piece of paper fall as quickly as possible?
Crumple the paper into a tight ball before dropping it. The increased surface area and air resistance of a flat sheet of paper slowed its fall, and crumpling it reduces both, allowing it to fall quicker.
Can a burned peice of paper ever be a sheet of paper again?
Nope. It has undergone a chemical change, and is no longer paper.
Is bleaching a sheet and pillowcase a chemical change or physical change?
These are chemical reactions (changes).
