One way that paper can be changed is by adding gloss to it. Glossed paper is very smooth and is mainly produced because you can't use lead on it, therefore keeping the paper clean and fresh. The only way you can write on glossed paper without damaging the gloss is by using a marker.

Paper can be chemically modified by adding substances like fillers or coatings to alter its properties, such as making it more water-resistant or improving its printing quality. It can also be mechanically processed by techniques like embossing or laminating to create textures or enhance durability for specific uses, such as packaging or decorative papers. These changes help paper meet various requirements for different applications.

What changes during a chemical change?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
Why the rusting of an iron pole is not physical change?
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
How has chemistry changed our daily lives?
All around us are chemical products: paper, cement, drugs, paints, solvents, etc.
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 the chemical change when a paper bag rips?
When a paper bag rips, the chemical composition of the paper does not change. The ripping of the paper bag is a physical change, where the arrangement of the paper fibers is altered, but the chemical bonds between molecules remain the same.

Does a physical or a chemical change?
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
Is cutting paper hearts from red paper a physical or chemical change?
Physical, because the paper hasn't changed any chemical properties (It is still paper), even after you cut a heart out of it.
How is paper a physical change?
Shredding paper is a physical change because you can put all the pieces of paper back together again, i.e. it is still paper. The chemical nature has not changed, only the APPEARANCE has changed.
Is paper making wood a physical or chemical change?
The process of making paper from wood involves both physical and chemical changes. Physically, the wood fibers are mechanically separated and broken down into pulp. Chemically, during the pulping and bleaching processes, chemical reactions occur to alter the composition of the wood fibers and remove impurities, resulting in the transformation of raw wood material into paper.
Is ripping up a piece of paper a chemical change?
No, ripping up a piece of paper is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties, while ripping paper only changes its physical appearance without altering its chemical composition.
Is ripping a piece of paper a physical or chemical?
It is physical because the appearance hasn't changed at all and is the same paper still. For example, if you burned the paper that would be a chemical change because the paper turned into ash and is releasing gas which is a resulting chemical change that has just happened. Hope this helped :) -V
How is shreadding paper a physical change?
Shredding paper is a physical change because it does not alter the chemical composition of the paper. The paper is simply being physically broken down into smaller pieces, but it is still made up of the same materials it was before shredding.
Is paper a reversible change?
No, paper undergoing a chemical change is irreversible. Once paper is burnt, it is permanently changed into ash and can't be turned back into its original form.
Is magnetizing a paper clip considered physical or chemical change?
