In a recent video clip posted on YouTube, one amateur scientist shows just just how chilly the weather is by revealing what happens once boiling water meets excessive cold. As he notes in the video\"s description, the temperature to be -41 degrees Celsius (or -41.8 Fahrenheit) in southern Porcupine, Ontario ~ above Thursday morning.

Using a water gun, the guy shoots the pipping hot water right into the cold winter air. After ~ the water leaves the plastic gun, that morphs into what looks favor mist.
Scientist and author Dr. Ainissa Ramirez explains that the hot water freezes -- changes from a liquid to a hard -- as quickly it comes into call with the cold air. That\"s why the water shows up like mist; it\"s no much longer water but many tiny ice crystals.
\"The very same can take place if friend toss the end water indigenous a cup native the ledge of the building. The people listed below will never feel it, due to the fact that the water will freeze ~ above the method down (to something prefer snow),\" Ramirez created in an email to The Huffington Post.

There\"s some debate in the scientific ar over whether hot or cold water freezes faster. Researcher as far back as Aristotle have noted occasions when warm water freezes at a quicker rate, an monitoring that came to be known as the Mpemba effect. (Singapore researchers recently offered an explanation for this phenomenon, yet scientists have not got to a consensus on why the result occurs.)
However, in this case, the science needs to do v the surface area of the hot water droplets. Together Wired noted, hot water is closer to steam than cold water, so when it\"s thrown right into cold wait it conveniently breaks into thin, tiny droplets each v a large surface area.
With larger surface areas, warm is expelled from the water an extremely quickly, leaving cool droplets. And, in extreme cold, the small droplets freeze prior to they close to the ground, leave a cloud of ice crystals.
