The Leidenfrost effect

The efficient transfer of heat from a solid to liquid is critical to many everyday devices: kettles: boilers: power stations and cars. If teh solid gets hotter the heat transfer improves, but if the solid gets too hot, the liquid vapourises, and vapor film forms between the liquid and the solid, reducing heat flow dramatically. This film formation is the Leidenfost effect.

Agreed, I don't find it patronizing. Heat transfer is a complicated subject, and most of it isn't common knowledge.

Your stove leans to the back.

That was not at all patronizing, it was educative, i liked it.

Are you a teacher? Because you talk in a slightly patronising way, like some teachers do.
