Why does water splash if you put it into a hot pan?
When you pour water on a very hot plate, much hotter than $100°$C, the water cannot touch the plate. It boils immediately, even before touching the plate. This makes a sudden and huge production of vapor, which takes much more room than a liquid : this throws the rest of the water anywhere in the vicinity with a great speed. It looks like an explosion. Some water may even be thrown to the ceiling.
Another famous experiment can be done directly on the electric plate, without a pan. If you pour maybe one milliliter water on a red hot plate, which has a small cavity in its center, the water floats above the plate in the cavity without touching it. For a couple of seconds, the vapor produced is not strong enough to eject the drop, which stays calmly in levitation. This effect is called Leidenfrost effect, or calefaction.
