Neither graphite nor diamond melt when heated - at a temperature of about 4800 °C, they sublime into gases. It takes a lot of energy to make them sublime as many strong covalent bonds need to be broken.

At which temperature does caffeine sublime?
caffeine will normally sublime around 180 degree C (at 1 atm).
How fast does mothball sublime?
depends on temperature. Very slowly at room temperature.
What temperature does iodine begin to sublime?
Vaporization of iodine occur after 113 oC.
Why are covalent compound volatile sublime?
There are some covalent compounds that are volatile and undergo sublimation such as iodine. Although, covalent compounds aren't always volatile. For example, diamond, the hardest solid known, does not change its phase even in a higher temperature around 3000 K.
What are physical properties of Xenon HexaFluoride?
At room temperature, xenon hexafluoride is a colourless solid. It will sublime into vivid yellow vapours.
Why does graphite sublime?
Graphite does not sublime or melt under normal room temperature. However; it does sublime if the temperature reaches 3652-3697℃.

What is the room temperature for a diamond?
A diamond at room temperature will generally be at the same temperature as the room.
What is the state at room temperature for a diamond?
A diamond at room temperature is a solid.
Is anything harder then a dimand?
there is nothing harder than a diamond and diamonds are sublime i.e they turn to vapour in extremely high temperatures

Which liquid can dissolve diamond?
No room temperature liquid can dissolve diamond.
As the temperature of matter rises what do most solids eventually do?
Most solids melt or sublime as the temperature rises. Melting is the more common effect but sublimation also happens.
Why does Iodine have a low boiling point but diamond has a high boiling point?
Diamond is an allotrope of carbon where all the carbon atoms are tetrahedrally bonded with each other forming a three dimensional covalent network. Since the bonds are strong (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
