In case of _______________ boiling, the liquid temperature is below the saturation temperature and the boiling takes place in the vicinity of the heated surface?
Correct answer: D. Local
- A. Nucleate
- B. Saturated
- C. Pool
- D. Local
Explanation
Local boiling occurs when the bulk liquid is below its saturation temperature but the liquid immediately next to the heated surface reaches saturation and forms bubbles. Nucleate boiling describes the bubble-forming mechanism, but the stated subcooled-bulk condition identifies local boiling.
