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 outenlayer of the diamond structure, preventing the conversion of diamond
to graphite.
Diamonds are thermodynamically unstable, but appear to be stable because the rate of conversion to graphite is
very slow.
Diamond is the stable form of carbon under normal conditions.
O A small amount of the diamond does convert to graphite; however, the equilibrium greatly favors the reformation
of diamond.
