In nonmetals such as diamond, thermal conductivity is created by lattice vibrations or atomic vibrations of the crystal to transfer energy . The atoms and bonds can be viewed as balls and springs connected together in a chain. When one end is heated, it starts to vibrate causing the next ball and spring to vibrate. This flows down the chain like a wave. The two factors affecting the efficiency of the heat transfer are the coupling between the atoms and how the waves propagate in the crystal and how the waves are scattered due to crystal imperfections. Diamond has extremely strong covalent bonds and so it has a high thermal conductivity [1].

Diamond has a high boiling point due to its strong covalent bonds between carbon atoms, requiring a large amount of energy to break them apart. These bonds are arranged in a three-dimensional network structure, making it difficult for the atoms to move and escape as a gas. This results in diamond having a high boiling point.
The molten form of diamond is not well understood. I don't believe that a sensible answer to this question is possible.
Diamond transforms into graphite as you heat it unless you keep the pressure really high. Some recent work (2008) on diamond high temperature and pressure avoiding this problem shows that it is possible to get molten diamond with solid diamond floating in it.

In a diamond you have covalent bonds between carbons these bonds are very strong and hence very strong to break. Diamonds do not actually melt they sublime.
While the forces that hold water molecules together in ice(mainly hydrogen bonding) are no where near as strong as the covalent bonds in carbon hence its melts at a much lower temperature.
Diamond has a very high melting point because each of the carbon atom is covalently bonded to the other four carbon atoms. The covalent bonds acting on them are very strong hence the high melting 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
because diamonds are not only made of carbon, wich is a non-metal, but are so dense, it takes longer for them to melt. also they might not melt at all, they might just burn!

What solid has a high boiling point is not malleable?
One example of a solid that has a high boiling point and is not malleable is diamond. Diamond is a form of carbon with strong covalent bonds arranged in a crystal lattice structure, which makes it extremely hard and with a high boiling point. Despite its hardness, diamond is not malleable because its crystal structure does not allow for easy deformation.
Can diamond be a gas?
Diamond cannot exist as a gas under normal conditions because it has a very high melting point and boiling point. Diamonds will typically convert into gas form through a process called sublimation at extremely high temperatures and low pressure.
What is the boiling point of giant covalent?
Giant covalent structures, such as diamond and graphite, do not have a specific boiling point because their atoms are held together by strong covalent bonds that require high temperatures to break. These structures do not boil in the traditional sense like molecular substances but rather decompose or undergo phase transitions at extremely high temperatures.
Is the boiling point of magnesium high or low?
The boiling point of magnesium is relatively high compared to other elements, at around 1,100°C (2,012°F). This is because magnesium has strong metallic bonds that require significant energy input to break in order to reach its boiling point.
Is it true that boiling point remain constant in all altitudes?
No, the boiling point of a substance varies with altitude. As altitude increases, atmospheric pressure decreases, causing the boiling point to decrease as well.
Does Diamond and graphite have boiling point?
Diamond does not have a boiling point because it sublimes directly from solid to gas at extremely high temperatures. Graphite also does not have a boiling point, as it too sublimes at high temperatures.
Why does Iodine have a low boiling point but diamond has a high boiling point?
Iodine has a low boiling point because it is held together by weak van der Waals forces, while diamond has a high boiling point due to its strong covalent bonds. The difference in bonding between iodine (a nonmetal) and diamond (a network covalent solid) contributes to their distinct boiling points.
What solid has a high boiling point is not malleable?
One example of a solid that has a high boiling point and is not malleable is diamond. Diamond is a form of carbon with strong covalent bonds arranged in a crystal lattice structure, which makes it extremely hard and with a high boiling point. Despite its hardness, diamond is not malleable because its crystal structure does not allow for easy deformation.
Why diamond is a non metal but it has high melting and boiling point?
Diamond is pure carbon with a specific crystalline structure.
What is diamond boiling point?
it has a boiling point of about 3700 degree Celsius
Is the boiling point of metalloids high?
The boiling point of metalloids is not so high.
Is the boiling point of covalent compounds high or low?
high boiling point low melting point
Why is diamond a unusual non metal?
Diamond is a unique nonmetal because its structure consists of a three-dimensional network of carbon atoms covalently bonded, making it extremely hard and having a high melting point. Additionally, diamond has a high refractive index and exceptional thermal conductivity, distinguishing it from other nonmetals.
Does chromium have a high or low boiling point?
Chromium has a high boiling point as opposed to nonmetals. Metals tend to have high boiling points.
Is 68 a high boiling point?
No, 68 is a low boiling point.
Is high melting point and boiling point a sign that a compound is ionic?
It's likely but not definitive. Giant covalent substances like diamond also have high melting and boiling points. To be sure you would have to show that the melted or dissolved substance conducts electricity.
Is high vapor boiling point a week intermolecular force?
Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.
