Hot water dripped onto cold water will vaporize immediately as positive temperature particles acquire negative temperature particle. The negative particle in orbit around the positive temperature particles, generates a gravitational field along its axis of rotation and acts against gravity. Hot water becomes a gas.
The same happens when hot water is poured out into the open at ambient \(-40^oC\), the steam observed is not water freezing immediately, but having acquired negative temperature particles, the hot water is weightless and drifts away like a mist.
Both experiments were posted on youtube.
Have a nice day.
