Buckminsterfullerene, has a lower melting point than diamond and graphite because it has a simple molecular structure. This means that unlike graphite and diamond the strong covalent bonds do not extend throughout the structure. The intermolecular bonds between molecules of C60 are easier to break and therefore it is much easier to separate C60 into it's individual molecules through the input of energy. However the covalent bonds between each atom of C60 is just as strong as the covalent bonds holding both diamond and graphite together, and similar amounts of energy would be required to split the three into it's individual atoms.

What are the key differences between the properties of diamond and graphite?
Diamond and graphite are both forms of carbon, but they have different properties. Diamond is a hard, transparent crystal with a high melting point, while graphite is a soft, opaque material with a lower melting point. Diamond has a three-dimensional structure, making it hard and durable, while graphite has a layered structure, allowing it to be used as a lubricant.
How do polymorphs of carbon differ in terms of their physical and chemical properties?
Polymorphs of carbon, such as diamond and graphite, differ in their physical and chemical properties due to their different atomic arrangements. Diamond is hard, transparent, and has a high melting point, while graphite is soft, opaque, and has a lower melting point. Additionally, diamond is a poor conductor of electricity, while graphite is a good conductor. These differences arise from the unique bonding structures of each polymorph.
What is the boiling point of graphite?
Carbon does not have a melting point it will turn directly into a gas at 3642 deg C. Diamond will turn to graphite at well below these temperatures at normal pressures so the sublimation point applies to both graphite and diamond.
Why does graphite have a high melting point?
As graphite has a giant lattice structure, it is very hard to break apart. Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state. Thus the melting point of graphite is high, same goes for diamonds.Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points.The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812,
What is the melting point graphite?
It is stable over a wide range of temperatures. Graphiteis a highly refractory material with a high melting point(3650°C.)in some experiments-it is turned out to be 4800 К ± 200 К.

Does graphite have a high melting and boiling point?
No, graphite has a relatively low melting and boiling point compared to other materials. It has a melting point of around 3,550°C and a boiling point of about 4,000°C, which are lower than metals like iron or copper.

Carbon does not have a melting point it will turn directly into a gas at 3642 deg C. Diamond will turn to graphite at well below these temperatures at normal pressures so the sublimation point applies to both graphite and diamond.
How is melting point of silicon dioxide lower than melting point of diamond?
The melting point of silicon dioxide (quartz) is lower than the melting point of diamond because silicon dioxide forms a more open structure, allowing for weaker forces between its molecules compared to the strong covalent bonds in diamond. This weaker bonding in silicon dioxide makes it easier for the molecules to move past each other and transition into the liquid phase at a lower temperature.

Would the melting point of caesium be higher or lower then sodium?
The melting point of cesium is lower than that of sodium. Cesium has a melting point of 28.4°C, while sodium has a melting point of 97.8°C.
An unknown compound gave a melting point of 230 Cwhen the liquid solidifiedthe melting point was redetermined and found to be 131Cwhat might have caused this change?
Pressure can affect melting points.However, assuming that your conditions are the same, you may have changed the crystal structure of your compound.The crystal structure of a compound can affect its melting point. For example, diamond and graphite are both forms of elemental carbon. Diamond is a face-centered cubic structure. Graphite, however, is hexagonal. Graphite has a melting point of 3652°C, whereas diamond melts at 3550°C. When you liquified your compound, it because amorphous and lost its crystal structure. It may have recrystallized into a different structure.Heating may also have effected a chemical change. If you saw bubbles or a color change, you likely made a new compound.
