So the lead of the pencil is made out of graphite, when i break the graphite what sort of bonds are broken? intramolecular or intermolecular bonds?
thanks in advance.
thanks in advance.
A pencil breaks when the graphite bonds holding the carbon atoms together become too weak to withstand the force applied to the pencil.
Graphite is used in pencils because it is a form of carbon that can easily leave marks on paper when rubbed against it. It also has a relatively low melting point, making it easy to shape into a pencil lead.
The graphite bonds break due to a combination of factors, such as pressure applied to the pencil, the quality of the graphite and the structural defects in the material. These factors weaken the bonds and eventually cause them to break.
No, once the graphite bonds have been broken, they cannot be repaired. The pencil may still be usable if the break is small, but the graphite bonds will not reform.
No, broken graphite bonds are not harmful to health. Graphite is a non-toxic form of carbon and the broken bonds pose no risk to human health.
