Exploring the Realms of water - The Leidenfrost effect ( #1 )

The skittering of water droplets of a hot surface that you just witnessed is known as the Leidenfrost Effect.

The effect can be seen as drops of water are sprinkled onto a pan at various times as it heats up. There is no specific temperature, beyond which the Leidenfrost effect kicks in.

Unveiling the mystery.

The bottom part of the water droplet vaporizes immediately on contact with the hot plate. 

The resulting gas suspends the rest of the water droplet just above it, preventing any further direct contact between the liquid water and the hot plate. 

As steam has much poorer thermal conductivity, further heat transfer between the pan and the droplet is slowed down dramatically. This also results in the drop being able to skid around the pan on the layer of gas just under it.

Mesmerizing, isn’t it ?
