Interpretation: The phase diagram that corresponds to a substance, which liquefies when pressure is increased below its freezing point is to be identified.
Concept introduction:
A phase diagram is a graph that represents the solid, liquid, and gaseous phases of a substance at different pressures and temperatures.
The lines are the boundaries between two phases and represent the conditions under which the two phases are in equilibrium.
At triple point, the three-phase boundaries meet each other.
The temperature at which a substance changes to vapor phase from a liquid phase at 1 atmis the normal boiling point.
The temperature at which a substance changes to liquid phase from a solidphase at 1 atmis the normal melting point
The temperature at which a substance changes to solid phase from a liquidphase at 1 atmis the normal freezing point.
