What would you like to do?
When a pencil is rubbed on paper fiction causes a small amount of the graphite from the core of the pencil to be left on the paper. This leaves a visible mark.
The answer depends on a variety of variables, but the simplest is that barring further action on the pencil mark (rubbing, wear, etc), it will last as long as the paper.
i dont know because im not smart ....
No. Lead used to be used in pencils but they stopped using it in them becasue of lead poisoning from pencils. Now they use graphite instead
It is a soft, dark material that shows up well on white paper and can be rubbed off.
they used rat fur
Yes, a scanner is like a copy machine. If it is on the paper, it will be copied into the digital image. You may use photo editing software to remove any marks or flaws t…hat you do not wish to keep.
Yes. All pencils use lead - not the element, but a graphite and clay mixture molded into a long narrow strip.
Graphite is used to make pencil lead, but it is not a form of coal.
Lead conducts eletricity so it is used in order to the computer could read it.
The graphite is reflective to the electronic beam.
I am not sure what a electrode is, but I substituted a wire for pencil lead and it worked, but it didn't work as well as a wire
a chromotagraphy is intended to split up a mixture of compounds into its subparts. if you use a pen, the ink will also be separated. that is why you use a pencil instead. Grap…hite (pencil lead) cannot be broken up into further components which can be separated by TLC and it is also not likely to cause reaction with any TLC components.
Static...as you write layers of graphite are sheared off and left on the page. The layer that touches the paper "sticks" and doesn't slide.
wooden pencils contain graphite which is an allotrope of carbon, not lead
