Film Boiling
If a surface heating the liquid is significantly hotter than the liquid then film boiling will occur, where a thin layer of vapor, which has low thermal conductivity, insulates the surface. This condition of a vapor film insulating the surface from the liquid characterizes film boiling.
In distillation, boiling is used in separating mixtures. This is possible because the vapor rising from a boiling fluid generally has a ratio of components different from that in the liquid.

Famous quotes containing the words film and/or boiling:
“This film is apparently meaningless, but if it has any meaning it is doubtless objectionable.”
—British Board Of Film Censors. Quoted in Halliwell’s Filmgoer’s Companion (1984)
“Unmeasured power, incredible passion, enormous craft: no thought
apparent but burns darkly
Smothered with its own smoke in the human brain-vault: no thought
outside; a certain measure in phenomena:
The fountains of the boiling stars, the flowers on the foreland, the
ever-returning roses of dawn.”
—Robinson Jeffers (1887–1962)
