What is added to graphite to make it watersoluble?
What is added to graphite to make water soluble pencils
Who is better thermal conductor diamond or graphite?
Graphite conducts far more electrical conductivity vise versa the diamond conducting far more thermal conductivity. Diamonds are hard. Graphite is soft.
Does graphite make diamonds?
No. Graphite and diamond are both allotropes of carbon, each with a different and distinct molecular structure.
What allotrope of carbon is used to make pencils?
yea. actually graphite, allitopes element of carbon. its not really all LEAD
Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What is special about graphite?
its hard
Is Graphite soft?
No, graphite is not soft. In fact, if you find a graphite rock, it is extremely hard. It is often very colorful, though.
What is the difference between charcoal graphite and diamond?
Diamonds are very hard, and graphite is very soft.
What is added to graphite to make it watersoluble?
What is added to graphite to make water soluble pencils
How hard is graphite on the hardness scale?
like a 7.
Can iron make pencils?
i don't think so,b'coz graphite is useful in pencil & iron is so hard so in what way we make pencil with iron.
The lead in a pencil is made from what mineral?
The "lead" is a mixture of GRAPHITE and CLAY. It is squirted out like spaghetti and baked hard.
What is the lead part of a pencil made of?
first step in pencil manufacture involves making the graphite core as the "lead". Back in the day we used lead which is toxic, the we switched to Graphite which is non-toxic. --------- It is frequently called "lead" as in "lead" pencils. But there is no lead in Graphite. Pencils simply contain a mixture of graphite and fine clay in varying proportions to make them hard or soft.
Who is better thermal conductor diamond or graphite?
Graphite conducts far more electrical conductivity vise versa the diamond conducting far more thermal conductivity. Diamonds are hard. Graphite is soft.
What elements make up graphite?
carbon
How hard is carbon?
That would completely depend upon the form of Carbon. Carbon can be found as coal, graphite, or diamond to name a few.
How is lead put into pencils?
First, the 'lead' in a pencil is not lead it is a mixture of graphite (a form of carbon) mixed with clay (the more clay the 'harder' the pencil). The lead portion is extruded in a long rod and then cut into lengths. The wooden sheath is made in two halves which are glued together round the lead.
