Which region is the fourth and final region of the pool boiling curve?

Explanation:
As the surface is heated, the pool boiling curve goes through four regimes in order: natural convection, nucleate boiling, transition boiling, and finally film boiling. The last region is film boiling, where a continuous vapor film forms between the hot surface and the liquid, insulating the surface and drastically reducing the heat transfer efficiency. This is the final, high-heat-flux regime on the curve.
