Thank you!

Solution

The Sublimation of compound is defined as the conversion of compound directly from the solid to gaseous form without going to the intermediate state that is the liquid state

The a region represents the solid state, b represents the liquid state and c represents the gaseous state

Since the conversion from a->c is only possible when the pressure is between 0-0.5 atm
