Thermal states: definition related to supersaturation Definition prompt: “The difference between the supersaturated temperature and the saturation temperature at the same pressure is called …” Choose the correct term.

Concept/Approach

• In nozzle flows, supersaturation refers to the fluid being below the saturation temperature (delayed condensation).
• The temperature deficit relative to saturation at the same pressure is the degree of undercooling (also termed supercooling).

Final AnswerDegree of undercooling
