Mist above the rimdrying pot · no liquid leaves the surface
Pressure starts a fresh experiment. The mist is liquid carried off the boiling surface: this cold room evaporates it, so the column has a top. After the pot dries, the curve follows an ideal heated vapor stream. Constant properties; pot heat and room losses excluded.
