Because if it's not an ink that will erase, u might make a mistake. Also there is a posibility that the ink might leak.:)
back in the edwardian period when people were storing their quills and ink, they were more like quill bags rather than pencil cases.
no, a pencil will float therefore it is less dense than water(ticonderoga #2 pencil was used)no pencils were harmed in the execution of this experiment
A book typically has more mass than a pencil due to the larger amount of material used to make the book compared to the pencil.
Yes, pencils typically float on water due to their low density and buoyancy. The wood and graphite materials used in pencils are less dense than water, allowing them to stay on the surface rather than sink.
While there are many metals that are not used in pencils, the one you are thinking of is probably lead. The part of the pencil known as the lead is actually a mixture of graphite (a form of carbon) and clay, rather than actual lead.
The element of pencil lead is graphite, which is not actually lead but rather a form of carbon. Graphite is a good conductor of electricity and is commonly used in pencils due to its ability to leave marks on paper.
Vaccines and diluents should not be used after the expiration date. The primary concern is sterility, rather than breakdown.
I did, I used the pencil sharpener and made the pencil sharper.
The stone used in a pencil is lead. x
Typically, a pen weighs slightly more than a pencil due to the mechanism and ink it contains. However, the weight difference is usually minimal and may vary depending on the specific pen and pencil being compared.
Pencils are preferred over pens when marking TLC plates because pencil marks are less likely to smear due to the solvent used in TLC development. Additionally, pencil marks can be easily erased and corrected if needed without affecting the results of the analysis.
pencil is use in chromography because the pencil is made from lead
