Folding a paper does not form new substances.
Physical.
Yes it's a physical change. No new substance is formed,
It is a physical change as the paper is still paper after you fold it.
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.
No. It is a physical change because there is no change in the chemical composition of the paper. If you were to burn the paper, that would be a chemical change called combustion, which would turn the paper into carbon dioxide and water, with the release of heat.

Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.

The current record for folding a piece of paper in half is 12 times, which results in 2^12 = 4096 layers. This record is constrained by the physical limitations of paper thickness and the properties of folding.
A change of shape caused by folding is a physical change because the substance retains its chemical composition. Cutting, on the other hand, is also a physical change as it does not alter the chemical composition of the material.
Tearing paper represents a physical and not a chemical change. Chemical bonds are not broken in this instance, but paper is physically separated (by force) from other paper.
