This exercise is intended to make students think about this issue, and to realize that. although diamond is commonly given the formula ‘C’ , this should not be taken to.

Carbon sublimes in a carbon arc which has a temperature of about 5,800 K (5,530 °C; 9,980 °F). Thus, irrespective of its allotropic form, carbon remains solid at higher temperatures than the highest melting point metals such as tungsten or rhenium.

Is it possible to melt diamonds? If you heat diamond in the open air, it will start to burn at around 700 degrees Celsius (1,292 degrees Fahrenheit), reacting with oxygen to produce carbon dioxide gas.

At normal atmospheric pressure, the melting point of diamond is 3550 degrees celsius (6422 F). 3823 Kelvin. 3550 Celsius. 6422 Fahrenheit. 3820 degrees Kelvin.

At about 100,000 atmospheres, diamond melts at about 4200 K, lower than the 4300 K mentioned above for graphite. However, if you look closely at the diagram, you will realize that at a little less than 100,000 atmospheres, where graphite is stable, its melting point is also 4200 K.

but it can be melted in the absence of air (or in vacuum) at a very very very high temperature. Since the melting point of diamond, the highest melting point required of any mineral -- 3820 degrees Kelvin -- a melted diamond is uncommon. Read more about the mineral diamond, below. Not humanly possible, but if temperatures reach (I will get back to you) it is possible. It is pressure dependant.

Carbon (from Latin: carbo coal) is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radioactive isotope, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

In graphite, each carbon atom is linked to three other carbon atoms by covalent bonds. In diamond each carbon atom is linked to four other carbon atoms by covalent bonds. So it seems paradoxical that diamond would have a lower melting point. There are Van der Waals forces between the layers of graphite but these are relatively weak in comparison to a covalent bond.
