This is a physical process.
Tearing a piece of paper is a physical change.
The paper can be uncrumpled. There was no chemical change that occurred, so its basic molecular structure is still the same.
stack up 100 of the same type of piece of paper, measure the thickness with a very accurate ruler, divide this thickness by 100
Depends on the type of paper.
Chemical and mechanical energy is used to cut a piece of wood.
Tearing a piece of paper is a physical change.
The paper can be uncrumpled. There was no chemical change that occurred, so its basic molecular structure is still the same.
The "piece of paper" is what is called 'virtual' it is a representative of a real piece of paper but is actually an image of one. The program that presents you with this virtual paper and allows you to type on it (an print what you have typed as a real bit of paper) is called a "word processing" application. This application must be present (installed) on your computer for you to be able to do this.
Medium sandpaper is best for sanding wooden furniture.

the paper undergoes combustion, a type of chemical reaction
A slide is a virtual piece of paper that you type on.
The function of the type writer is to print your desired combination of words on a piece of paper.
First get the fuel rod. Then type in the coordinates you have on the piece of paper you found.

Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
Burning paper is a chemical change. The paper reacts with Oxygen in the atmosphere to produce Carbon Dioxide, Water and other compounds [exactly which other compounds is dependent upon the composition of the burnt paper]
