Leidenfrost temperature
The Leidenfrost temperature is the specific temperature at which a liquid, like water, forms a vapor layer when it comes into contact with a hot surface. This vapor layer insulates the liquid from the surface, causing the droplet to hover and move more easily, often appearing to dance or skitter. Essentially, it’s the temperature at which the boiling process changes from simple surface boiling to a rapid vapor cushion that reduces direct contact. This phenomenon affects how quickly a liquid heats up and evaporates and is important in various heat transfer applications.
