Graphite is a gray crystalline form of carbon. Although a solid, it's molecules are able to slide over each other.
For this reason, graphite has two main uses:

  1. as lubricant in engineering
  2. as the main ingredient of the 'lead' in pencils.
Chemically/physically, graphite is described as a layered compound, and the layers are only fractions of a nanometer apart. Consequently the layers can be easily removed by slight friction. By brushing a block of graphite against paper, for example, marks will be made on the paper.
With a little more expertise, the marks can be controlled to make writing, which is made even easier if the graphite can be wrapped in something we can hold with our hands/fingers, but which doesn't shed its molecules so readily.

Wood would be good.

Graphite is therefore the ideal material for making pencils, where a little friction transfers molecules of graphite to the paper, to make marks of our choice.

So, graphite can be used to write a short story!

The peptidoglycan of the bacterial cell wall contains a carbohydrate matrix linked together be short chains of what?

The peptidoglycan of the bacterial cell wall contains a carbohydrate matrix which is linked together by short chains of peptides. These peptides consist of alternating amino sugars, such as N-acetylglucosamine and N-acetylmuramic acid, and amino acids.

How does the shape of graphite in cast iron affect its properties?

The shape of graphite in cast irons has the following basic forms: (a) Flakes. Graphite flakes have sharp edges which act as stress raisers in tension. This shape makes cast iron low in tensile strength and ductility, but it still has high compressive strength. On the other hand, the flakes also act as vibration dampers, a characteristic important in damping of machine-tool bases and other structures. (b) Nodules. Graphite can form nodules or spheroids when magnesium or cerium is added to the melt. This form has increased ductility, strength, and shock resistance compared to flakes, but the damping ability is reduced. (c) Clusters. Graphite clusters are much like nodules, except that they form from the breakdown of white cast iron upon annealing. Clusters have properties that are basically similar to flakes. (d) Compacted flakes. These are short and thick flakes with rounded edges. This form has properties that are between nodular and flake graphite. © 2008 Pearson Education, Inc., Upper Saddle River, NJ. All rights reserved.


What is the word props short for?

The word "props" is short for "properties". Properties is an old word--Shakespeare uses it in A Midsummer Night's Dream with the same meaning.


What is formed when 5 amino acids are joined together?

When five amino acids are joined together, a molecule called a peptide is formed. Peptides are short chains of amino acids linked by peptide bonds. As the chain grows longer, it becomes a polypeptide.

What is an olygopeptide?

An oligopeptide is a short chain of amino acids, typically consisting of 2 to 20 amino acids linked together by peptide bonds. These molecules are smaller than proteins, which are composed of longer chains. Oligopeptides play various roles in biological processes, including acting as hormones, signaling molecules, and precursors to larger proteins. Their specific functions and properties depend on the sequence and composition of the amino acids they contain.


What does props mean in real estate?

During DNA replication the short sections of new DNA known as okazaki fragments which are eventually linked together by ligase?

Yes, during DNA replication, the lagging strand is synthesized in short fragments called Okazaki fragments. These fragments are later joined together by DNA ligase to produce a continuous strand. This process helps to ensure accurate and efficient replication of the entire DNA molecule.

Does 'together' have a short g sound?

No, the word "together" does not have a short 'g' sound. It is pronounced with a 'th' sound at the beginning, followed by a short 'uh' sound, and then a 'th' sound again.
