When vaporisation takes place through a blanketting film of gas, the phenomenon is termed as ___________________ boiling?
Correct answer: C. Film
- A. Pool
- B. Nucleate
- C. Film
- D. Transition
Explanation
When a stable vapour or gas blanket separates the hot surface from the liquid, the process is called film boiling. Nucleate boiling instead involves bubbles forming directly on the heated surface without a continuous insulating film.
