What are the static and kinetic coefficients of friction between flint and high carbon steel?
The static coefficient of friction between flint and high carbon steel is typically around 0.6 to 0.8. The kinetic coefficient of friction between the two materials is slightly lower, usually around 0.5 to 0.6. Keep in mind that these values can vary depending on factors such as surface roughness and contact pressure.

Why doesn't anything stick to Teflon and how does this property relate to friction?
Teflon has a nonstick property because its surface is very smooth and has low friction. This is due to the strong chemical bonds between the carbon and fluorine atoms in Teflon, which repel other substances. This low friction property reduces the resistance between surfaces, making it difficult for anything to stick to Teflon.
How does graphite reduce friction?
low shear strength
What is in fossil fuel and released in the form of kinetic energy when burned?
The heat is produced by the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen. So CO2 and water are the necessary products when fossil fuel is burned, without which there would be no heat.
Does wave energy create carbon dioxide?
No, wave energy does not directly create carbon dioxide. It is a renewable energy source that generates electricity using the kinetic energy of ocean waves, which is clean and does not produce carbon dioxide emissions during operation.
Why brushes are made up of carbon?
Carbon brushes are commonly used in electrical systems due to their high conductivity, resistance to heat, and ability to easily adjust to different commutator surfaces. The carbon material offers low friction and wear properties, making it ideal for transferring current in electric motors and generators. Additionally, carbon brushes provide a stable performance over time and have a long service life.
Teflon is the most slippery substance in the world?
Teflon is known for its low friction properties, making it highly slippery. Its non-stick characteristic comes from its unique molecular structure, which allows substances to slide easily over its surface. While it is one of the slipperiest substances, there are other materials like diamond-like carbon that can exhibit even lower friction coefficients.
What happens when a penny comes in contact with carbon?
When a penny comes in contact with carbon, such as in the form of graphite in a pencil, the two materials do not chemically react. The friction between the penny and carbon can cause a transfer of material, leaving a mark on the penny.
Who has greater kinetic energy a hydrogen atom or a carbon atom moving at the same speed?
The carbon atom would have greater kinetic energy compared to the hydrogen atom because kinetic energy is directly proportional to the mass of the object. Since the carbon atom is heavier than the hydrogen atom, it would possess more kinetic energy when moving at the same speed.
What type of kinetic energy is released when the gas in a car is burned?
carbon dioxide or carbon monoxide
What correctly describes the difference in kinetic energy between the two cars?
The kinetic energy of a moving object is determined by its mass and speed. If two cars have different masses but the same speed, the car with the greater mass will have more kinetic energy. If they have the same mass but different speeds, the car moving faster will have more kinetic energy.

What is slippery carbon?
Slippery carbon refers to a form of carbon that has a low coefficient of friction, making it slippery to the touch. This type of carbon is often used in lubricants and coatings to reduce friction and improve performance in various industrial applications.
What has the author Donald Roger Breckenridge written?
Donald Roger Breckenridge has written: 'A Study of the Capture Coefficients of Nitrogen and Carbon Dioxide'
What man made substance has the lowest common coefficient to friction?
Diamond-like Carbon has a coefficient of friction of as low as 0.05 on polished steel.
How does graphite reduce friction?

What are the stoichiometric coefficients for the combustion of ethanol?
The balanced chemical equation for the combustion of ethanol is C2H5OH + 3O2 -> 2CO2 + 3H2O. Therefore, the stoichiometric coefficients are 1 for ethanol, 3 for oxygen, 2 for carbon dioxide, and 3 for water.
What is dry carbon lubricant?
Dry carbon lubricant is a type of lubricant that contains solid carbon particles suspended in a carrier fluid. It is applied to reduce friction between surfaces without using oil or grease. Dry carbon lubricants are often used in applications where oil-based lubricants are not suitable, such as high-temperature environments or where cleanliness is important.
