Which outcome occurs when exceeding the Leidenfrost point of water on a heated surface?

💡 Explanation

Heat transfer drops significantly because a vapor layer forms, causing film boiling; this vapor layer’s poor thermal conductivity hinders heat flow to the liquid water, therefore reducing transfer, rather than promoting quenching or enhancing boiling as occurs at lower temperatures.
