← ScienceWhich consequence results when exceeding the Leidenfrost point?
A)Rapid heat transfer rate decrease✓
B)Nucleate boiling becomes more efficient
C)Fluid enthalpy reaches maximum value
D)Convection currents maximize quickly
💡 Explanation
Exceeding the Leidenfrost point causes a vapor layer to form isolating the liquid from the hot surface; this 'film boiling' drastically decreases Film Boiling heat transfer, because the latent heat transfer mechanism is diminished, therefore transfer decreases, rather than alternatives under cooler conditions before reaching it.
