The liquid no longer makes direct contact with the surface; instead, the insulating vapor layer drastically slows heat transfer.
The Leidenfrost effect describes the remarkable behavior of a liquid that encounters a surface significantly hotter than the liquid’s boiling point, creating a momentary suspension between the two that makes the drop hover, dance, and glide rather than evaporate instantly. When a droplet reaches the temperature at which its bottom layer vaporizes so rapidly that a stable
