Question

The phase diagram for a pure substance is given below.  The substance is stored in a container at 150 atm at 25 $\degree$C.Describe what happens if the container is opened at 25 $\degree$C.

Quizplus · Accepted Answer

At 150 atm and 25°F (-4°C), the substance is in the liquid phase. If the container is opened at the same temperature, the pressure will decrease to atmospheric pressure, causing the substance to undergo vaporization (evaporation) and escape as a gas. Therefore, the best choice is E, "The liquid in the container vaporizes."
