This is the pressure corresponding to the maximum temperature above which liquid cannot be formed regardless of pressure.

This is the pressure corresponding to the maximum temperature above which liquid cannot be formed regardless of pressure.

• A. Cricondenbar
• B. Cricondentherm pressure
• C. Critical pressure
• D. Condensation pressure

Answer: (B)

In phase diagrams of liquid–vapor systems, there are upper limits to where liquid and vapor can coexist. The highest temperature at which liquid and vapor can be in equilibrium is called the cricondentherm. The pressure that corresponds to this maximum temperature on the boundary is known as the cricondenbar. This means that above the cricondentherm temperature, liquid cannot form regardless of pressure, and the system is effectively supercritical. Some sources colloquially refer to the pressure at that point as cricondentherm pressure, but the standard term is cricondenbar. Recognizing the distinction helps you interpret how temperature and pressure limits define the liquid–vapor region on a phase diagram.
