Why is graphite used as a pencil lead? View Solution Thermodynamically graphite is more stable than diamond but diamond does not transform into graphite on its own. Why? View Solution Assertion (A): Enthalpy of graphite is lower than that of diamond. Reason (R ) : Entropy of graphite is...

However the process takes millions of year, so at these normal standard conditions, graphite is a much stable form of carbon then diamond. Yeah. If it burns in air carbon dioxide gas formed. The aqueous solution of graphite is known as Aqua dog first stop graphite is also known as plumbago...
The contrast between diamond and graphite is particularly striking; graphite, which is built up of loosely-bound stacks of hexagonal sheets, appears to be more than twice as good at soaking up thermal energy as diamond, in which the carbon atoms are tightly locked into a three-dimensional ...
Metamorphic graphite inherits the carbon isotopic composition from its organic precursor40 that can also explain the different carbon isotope composition of diamonds in the two rocks as a feature inherited from the source.Solid-state transformation of graphite into diamond requires high activation energy ...
Quartz glass is used in the manufacturing of optical devices, lighting systems, refractory materials, and chemical apparatuses. One must observe proper precautions when handling quartz glass to protect its reliability. The glass must be kept clean all the time. Its thermal behavior must be taken in...
Give the normal state (solid, liquid, or gas) carbon (graphite). Is it important to know the boiling point of a solid? A solid is cooled to a very low temperature. Assuming the mass remains constant, how, if at all, does this affect the density of the solid?...
Arrange carbon atoms in one way, and they become soft, pliable graphite. Rejigger the arrangement, and — presto! — the atoms form diamond, one of the hardest materials in the world. Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and...
It can combine in ways that create compounds as hard as diamond, or can combine to make slippery substances like graphite. It is the sixth most abundant element present in the entire universe.Answer and Explanation: Carbon is the backbone of organic chemistry because of its position in the ...
