carbon has negative temperature coficient so its resistance decrease with the rise of temperature in contrast of copper....carbon has has lubrication property so it offered less friction as compared to copper....

What is made when you mix sulfuric acid copper carbonate?
Using cupric oxide (CuO, copper(II) oxide), a black powder, it will make hydrated copper sulfate (CuSO4.5H2O -blue crystals) anything left over is simply un-reacted chemical. As the excess water evaporates and if heated it will make anhydrous copper sulfate (CuSO4) a white powder.
Why is biomass a better alternative than coal?
The main advantage of biomass over coal is that it is "carbon neutral". This means that in order for the biomass to be created, it consumed carbon dioxide from the environment. Upon burning biomass, no additional carbon is added to our atmosphere. Coal, on the other hand, is taking carbon out of the earth and adding more to our atmosphere.
Does copper wire snap when it is over a flame?
no
What happens when you pour copper over iron?
nothing
When hydrogen gas passed over heated cupric oxide?
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
What is the use of a copper bird bath?
A copper bird bath is a copper vessel that holds water for birds to bathe in. One advantage of a copper bird bath over an iron bird bath is that copper does not rust.
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
What advantage does solar power have over biomass?
Solar power produces no carbon dioxide
What is an advantage of solar energy over coal?
It does not release pollution such as carbon dioxide and sulfur dioxide.
What are the advantages of wireless over copper or fiber connections?
The great advantage is avoiding the need for managing cables and all the implied costs.
What advantage does solar energy have over fossil fuels?
Solar energy emits no carbon dioxide emissions. It is free and renewable.
Which is the heaviest mild steel or copper?
metal with out the properties that combine and then materialize into a base form of solid mass, or as known as carbon emulsified over and over repeatedly becomes a hairline, unlike brass metal.
What is the plural possessive of brush?
It depends on which type of brush you mean. If you men a brush as in a shrubbery, then the word brush is plural and singular. To be lost in the brush implies that you are in an area that is full of bushes or shrubberies. If you mean a brush that you use in your hair, then the plural is brushes.
Are diamonds made from copper?
Diamonds are formed from carbon. Copper is formed from its metallic atoms. Both are formed deep within the Earth's mantle, under extreme pressure over millions, possibly billions of years.
