What is Diamond’s melting and boiling point?
1 Answer. Diamond (carbon) does not melt at 1 atm. It sublimes to vapor. Using carbon’s theoretical phase diagram below (from Wikimedia), “liquid diamond” could be achieved at about 10 GPa (99 thousand atmospheres) and 5000 K (4700 °C).
What is Diamond’s melting point?
7,280° FahrenheitIn the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Why do most metals have high melting and boiling points?
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
Which is harder graphite or diamond?
Both graphite and diamond are made only of carbon atoms. Graphite is very soft and slippery. Diamond is the hardest substance known to man.

Has high melting and boiling point?
Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to see how bonding and structure are related to the properties of substances. Energy must be transferred to a substance to make it melt or boil.
What are 3 facts about carbon?
9 Essential Facts About CarbonIT’S THE “DUCT TAPE OF LIFE.” … IT’S ONE OF THE MOST ABUNDANT ELEMENTS IN THE UNIVERSE. … IT’S NAMED AFTER COAL. … IT LOVES TO BOND. … NEARLY 20 PERCENT OF YOUR BODY IS CARBON. … WE DISCOVERED TWO NEW FORMS OF IT ONLY RECENTLY. … DIAMONDS AREN’T CALLED “ICE” BECAUSE OF THEIR APPEARANCE.More items…
What are 4 properties of carbon?
The Chemical Properties of Carbon are as follows:Chemical Formula: C.Oxidation: Combines with oxygen to produce carbon dioxide (CO2 ) and carbon monoxide (CO)Reactivity: Carbon does not dissolve in, or react with, water or acids.Chains of Atoms: Carbon has the ability to make long strings, or chains, of atoms.More items…
What’s the boiling point of carbon?
4,827 °CCarbon/Boiling point
What material has the highest melting point?
tungstenThe chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as filaments in light bulbs.
Why does carbon have a high melting and boiling point?
However, graphite still has a very high melting and boiling point because the strong covalent bonds that hold the carbon atoms together in the layers require a lot of heat energy to break.
Why does Al have a high melting point?
Melting and boiling points rise across the three metals because of the increasing strength of the metallic bonds. The number of electrons which each atom can contribute to the delocalised “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium to magnesium to aluminium.
What is graphites melting and boiling point?
Physical Properties Graphite has a melting point similar to that of diamond of around 3600°C, at which point it sublimes rather than melting.
Why Lead has low melting point?
Melting points and boiling points The trends reflect the increasing weakness of the covalent or metallic bonds as the atoms get bigger and the bonds get longer. The low value for tin’s melting point compared with lead is presumably due to tin forming a distorted 12-co-ordinated structure rather than a pure one.
Does chlorine have a high melting point?
-101.5 °CChlorine/Melting point
What factors affect melting point?
TL;DR (Too Long; Didn’t Read) Molecular composition, force of attraction and the presence of impurities can all affect the melting point of substances.
What factors affect boiling point?
The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin.
Which has a higher melting point graphite or diamond?
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.
Does carbon have a high melting point?
Moreover, carbon has the highest melting/ sublimation point of all elements. At atmospheric pressure it has no actual melting point as its triple point is at 10 MPa (100 bar) so it sublimates above 4000 K.
Which metal have high melting and boiling point?
TungstenThe free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the elements discovered, melting at 3,422 °C (6,192 °F; 3,695 K). It also has the highest boiling point, at 5,930 °C (10,710 °F; 6,200 K)….TungstenNamed byTorbern Bergman (1781)Main isotopes of tungsten52 more rows
