← ScienceWhich effect occurs when exceeding the Leidenfrost temperature?
A)Increased thermal resistance and heat transfer✓
B)Rapid homogeneous nucleation into ice
C)Reduced vapor film thickness, promoting boiling
D)Enhanced surface wetting and nucleate boiling
💡 Explanation
Reaching the Leidenfrost temperature causes film boiling because a stable vapor layer forms and thermally insulates the liquid from the hot surface. Therefore, less heat is transferred, rather than more, since contact is minimized.
