The phase diagram for carbon indicates the extreme conditions that are needed to form diamonds from graphite. At 2000 K, what is the minimum pressure needed before graphite changes into diamond? Carbon phase diagram P- atm 10 Solid 1 (diamood) 10- Liquid 104 Pibar 10 Solid 11 10- (graphite) Gas 10-1 1 0 1000 2000 5000 6000 3000 4000 TiK) What is the minimum temperature at which liquid carbon can exist at pressures below 109 atm?

What is the temperature and pressure of the diamond, liquid, and graphite triple point? atm T= K P= Why is it that people can wear diamonds under normal conditions without having to keep them under high pressure? O A thin layer of oxidized carbon forms on the outer layer of the diamond structure, preventing the conversion of diamond to graphite A small amount of the diamond does convert to graphite; however, the equilibrium greatly favors the reformation of diamond Diamond is the stable form of carbon under normal conditions. Diamonds are thermodynamically unstable, but appear to be stable because the rate of conversion to graphite is very slow
