Diamond melts or vaporizes above about 4000 deg C. If the pressure is high enough it is liquid, if lower it is a gas. If heated in air diamond will burn above about 850 deg. C becoming carbon dioxide also a gas.
When a diamond is burned, it does not turn into coal. Instead, it undergoes combustion and forms carbon dioxide gas, leaving behind a small amount of ash residue. Coal is a completely different substance that forms over millions of years from plant matter undergoing pressure and heat.
A diamond can be cut by another diamond, or polished into powder using a diamond wheel. Neither is recommended for an at-home trial.
Diamond is not completely fireproof but it has a very high melting point of 3,827 degrees Celsius (6,900 degrees Fahrenheit), which means it is highly resistant to heat. However, if exposed to extreme temperatures, such as in a fire, diamond can eventually burn and turn into carbon dioxide gas.
No, diamond and graphite do not form the same product when burnt. Diamond will convert into carbon dioxide gas, while graphite will also convert into carbon dioxide gas.
Graphite does not undergo a chemical change when exposed to heat, so it does not "turn into" something else. Instead, it transitions directly from a solid to a gas through a process called sublimation.

Lavoisier showed that by concentrating the Sun's rays (through a magnifying glass), on a diamond in an oxygen atmosphere, that diamond could be burnt, and gave off the same quantity of CO2 as would a piece of carbon. The temperature for this combustion starts around 700 oC. In an inert gas, diamond will revert to graphite at about 1700 oC.

All diamonds are formed from carbon, which is not a gas.
A gas can't turn directly into a solid but a solid can turn into gas for example ice to water vapor.
NO!
Solid
To turn off the gas in case of an emergency, locate the gas shut-off valve near the gas meter and turn it clockwise to shut off the gas supply.
No,The process in which turns coal into diamond cannot be reversed or "undone"
my answer is how many days does coal turn into diamond 3nfgerhg8788
turn completely white and dance in the diamond shop
