Question

Can diamond sublime at any pressure up to 10^11 kPa? Explain your answer.

O Yes, it can sublime to the liquid state
• Yes, it can sublime to graphite.
• No, it cannot sublime because diamond doesn't have a triple point.
• No. It cannot sublime because the gas phase is not adjacent to diamond.

No, diamond cannot sublime at any pressure up to 10^11 kPa. Sublimation is a process where a substance transitions directly from a solid to a gas without passing through the liquid state. Diamond does not have a triple point, meaning there is no specific pressure and temperature at which solid diamond, liquid diamond, and diamond gas can coexist in equilibrium. Therefore, diamond cannot undergo sublimation to the gas phase under any pressure up to 10^11 kPa.
