← ScienceWhich outcome occurs when a cryogenic fluid exceeds the Leidenfrost Point threshold?
A)Film boiling substantially reduces heat✓
B)Nucleate boiling maximally boosts transfer
C)Conduction becomes the primary transfer
D)Critical point prevents phase transformation
💡 Explanation
Film boiling occurs because the Leidenfrost effect insulates the hot surface with vapor, substantially reducing heat transfer rather than increasing it; therefore film boiling is the consequence under such cryogenic conditions, as opposed to enhanced nucleate boiling.
