Under which circumstances will graphite be used as a lubricant instead of grease Explain?
There are a few reasons why graphite might be used as a lubricant instead of grease. One reason is that graphite can withstand higher temperatures than most greases, so it can be used in applications where the temperature is too high for grease. Another reason is that graphite has low friction, so it can be used to reduce wear and tear on moving parts. Finally, graphite is chemically inert, so it won't react with other materials it comes into contact with.
Graphite is used as a lubricant in situations where high temperatures or chemical reactivity would make grease ineffective or undesirable. Graphite has a high tolerance for heat and can withstand strong chemicals, making it suitable for extreme conditions where traditional lubricants like grease would break down or become ineffective.

What material used in pencils instead of lead?
Graphite is the material used in pencils instead of lead. Graphite is a form of carbon that leaves marks on paper when it is used in a pencil. Contrary to popular belief, pencils do not contain lead.
What does graphite turn into?
Graphite does not undergo a chemical change when exposed to heat, so it does not "turn into" something else. Instead, it transitions directly from a solid to a gas through a process called sublimation.
Is lead used in pencils?
Lead is not used in pencils. Instead, pencils contain graphite, which is a crystalline form of carbon that leaves a gray mark on paper when used. The term "lead pencil" is a misnomer that dates back to when graphite was mistaken for a form of lead.
How is lead put into pencils?
Lead is not used in pencils; instead, a mixture of graphite and clay is encased in wood to create the "lead" of the pencil. The term "lead" for the pencil core is a misnomer dating back to when blocks of graphite were used in the 16th century.
What is in batteries stained glass windows and old paint but not in pencils?
Lead is. people often mistake the graphite in pencils for lead. Lead is used in batteries, in stained glass as the piece bonder, and in old paint. Lead is banned for use in paints, water pipe systems, and much more. Lead flashing is still allowed in building construction.
What is The predecessor of the graphite pencil?
The predecessor of the graphite pencil was the lead pencil, which used a mixture of graphite and clay for the core instead of just graphite. Lead pencils were first developed in the 16th century.
Do you get lead poisoning from eating colouring pencil sharpens?
No you cannot. Lead is not used in pencils, graphite is used instead. Graphite and clay is used and the proportion of graphite to clay is adjusted according to the hardness required.
What material used in pencils instead of lead?
Graphite is the material used in pencils instead of lead. Graphite is a form of carbon that leaves marks on paper when it is used in a pencil. Contrary to popular belief, pencils do not contain lead.

What looks like a ink pen but uses pressure instead of ink to write?
A pencil looks like an ink pen but uses pressure from a graphite core to write instead of ink. The graphite is dispensed onto the paper as you apply pressure, simulating the writing action of an ink pen.
Is graphite lead conductive?
Graphite itself is pure carbon. But it might be possible for some samples of graphite to contain impurities of lead.
How bacteria could be useful instead of hazardous?

What does SGI on a engine block mean?
Spheroidal Graphite (Cast) Iron. As the name implies, graphite is present in spheroidal form instead of flakes and compared with Grey Cast Iron it has higher mechanical strength, ductility and increased shock resistance.
How can you improve upon the crayon invention?
It has already been improved. Pencils have many colors and hardness values. Pens are a type of pencil with ink instead of graphite.
Which is used as a moderator in nuclear reactor?
Most current power plants use water, but heavy water, graphite, hydrocarbons, etc. could be used instead.
