What else can I help you with?
How might school be different if the Earth's supply of graphite ran out?
What is referred to as "pencil lead" is actually graphite. Lead is a much too toxic substance to be used in pencils. If the world's graphite supply were top run out there would be no more pencils in school or anywhere else.
What is the commonly used medium for drawing?
Graphite pencils are commonly used as a medium for drawing.
What elements located in group 14 is used for making pencils and carbon?
Confusing question. You don't "make" carbon, but one particular form is used for pencils, graphite.
Who invented the slate pencil?
The slate pencil, typically made of a mixture of graphite and clay, does not have a single inventor but rather evolved over time. Its origins can be traced back to the use of graphite in the 16th century, particularly in Borrowdale, England, where natural graphite was first mined and shaped into writing instruments. The modern manufacture of slate pencils began in the 19th century as the demand for durable writing tools increased.
Where and when was the pencil invented?
Some time before 1565 (some sources say as early as 1500), an enormous deposit of graphite was discovered on the approach to Grey Knotts from the hamlet of Seathwaite in Borrowdale parish, Cumbria, England. The locals found that it was very useful for marking sheep. This particular deposit of graphite was extremely pure and solid, and it could easily be sawn into sticks. During the Napoleonic Wars, German and English pencils were not available for the French were unable to import the graphite sticks. So in 1795, N. J. Conte (Nicholas Jacques Conté, an officer in Napoleon's army) discovered a method of mixing powdered graphite with clay and forming the mixture into rods that were then fired in a kiln. By varying the ratio of graphite to clay, the hardness of the graphite rod could also be varied.
Is wad graphite?
Graphite is a form of carbon that is composed of layers of graphene. It is a good conductor of electricity and heat, and is commonly used in pencils, lubricants, and as a component in batteries.
What uses does graphite have in everyday life?
Graphite is commonly used in everyday life for writing and drawing purposes in pencils. It is also used for lubrication, as a component in batteries, and as a conductor in electronics. Additionally, graphite is used in thermal management applications, such as in the production of heat sinks for electronics.
What products might copper and graphite be best suited for?
Copper is commonly used in electrical wiring and plumbing due to its high conductivity and corrosion resistance. Graphite, on the other hand, is often used in lubricants, batteries, and as a component in pencils due to its low friction properties and electrical conductivity.
How can graphite be used?
Graphite can be used as a lubricant due to its low friction properties. It is also used in pencils for writing and drawing. Additionally, graphite is an important component in batteries, especially in lithium-ion batteries used in electronic devices.
What is the role of carbon in pencils?
Carbon is the main component in pencils, specifically in the form of graphite. It is responsible for leaving marks on paper when the pencil is used.
What can you use Graphite for?
Graphite is commonly used in pencils, as a lubricant in locks and hinges, as a dry lubricant in industrial applications, and in batteries and fuel cells as a conductive material. It is also used as a component in refractory materials and brake linings due to its high-temperature resistance.
What are the properties and uses of graphite as a solid type material?
Graphite is a form of carbon known for its properties of being a good conductor of electricity and heat, as well as having a slippery texture. It is commonly used in pencils, lubricants, batteries, and as a component in various industrial applications such as in the production of steel and in nuclear reactors.
Is graphite a giant metallic?
Graphite is an allotrope of carbon and is semi metallic. It is a very good conductor of electricity and is also used for steel making, in batteries, brake lining and in pencils.
Do they use lead or graphite for mechanical pencils?
Mechanical pencils, like the regular kind of pencils, use graphite.
What is grafite?
Graphite is a crystalline form of carbon that is used in pencils and as a lubricant. It is composed of layers of carbon atoms arranged in a hexagonal lattice structure. Graphite is a good conductor of electricity due to its arrangement of carbon atoms.
What is graphite used in?
pencils such as lead pencils
What is found in graphite?
Graphite appears naturally in three forms: amorphous, which is the last stage of the coalification process; crystalline flake, which is used in brake linings and pencils; and lump, used mostly in batteries
