Is Transferring graphite from a pencil to paper when writing physical or chemical?

Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
What Chemical change is mixing flake graphite with oil?
your mixing two chemicals together so of course its a chemical change
Is the transferring of Na to Cl to complete octets for both a physical or chemical change?
It is simply a chemical change.
When you hit a piece of graphite and break it into small pieces you have broken chemical bonds?
This is FALSE ! Because you only broke it in pieces and tearing or breaking into pieces is a PHYSICAL CHANGE not a chemical change. ---------------------------- I also consider that breaking graphite is only a physical change. - - - - --------------------- It's true, you break chemical bonds when you break pieces of graphite. Graphite is a macromolecule: it is found in sheets, and within the sheets each carbon atom is bonded to four other carbon atoms. The only way you could possibly get it apart is to break the bonds between atoms.
Is it a chemical change if you draw a picture with a pencil?
No, because graphite is structured in such a way that the layers glide. Whilst drawing with a pencil the layers are gliding which is leaving a mark on the paper, because the substances inside the pencil are being rubbed off. Hence, this is a physical change rather than a chemical change. The graphite remains graphite, the paper remains paper.
Is graphite conducts electricity is an example of chemical or physical change?
Yes
Is graphite lubricant a chemical or physical property?

Is writing with pen a chemical change?
Writing with a pen involves a physical change rather than a chemical change. A chemical change involves the formation of new substances with different chemical properties, while in writing with a pen, the ink is simply transferred onto the paper without any chemical reactions occurring. The ink may undergo physical changes such as drying or adhering to the paper, but the chemical composition of the ink remains the same.
Why is shapening a pencil a physical change?
no new chemical products are formed .there is only a change in shape .the products after and before are same that is wood and graphite
What is a symbolic way to write out a chemical change?
