It is an amazing moment when boiling water turns into an icecloud after being dropped into the air at below-zero temperatures.
In Alberta Canada, footage shows a resident throwing boiling water at his head. This was to check the Mpemba Effect on December 27, 2007.
As the man gazes with awe, the water transforms into an arc made of ice over his head.
The boiling water becomes snowflake after being touched by the frozen air.
After he has thrown the boiling water on his head, he watches it transform into ice in Alberta (Canada) on December 27,
Following contact with the icy atmosphere, the boiling water turns immediately into an arc of white ice over his head.
Mpemba Effect is a theory that cold liquids will freeze quicker than hot ones.
It was named after Erasto Mpemba from Tanzania who noted a Hot ice cream was faster to freeze than cold during his 1960s cookery class.
The effect has been noted since the time of Aristotle in Ancient Greece but scientists have struggled to explain why the phenomenon happens.
In 2016, a team of Singapore scientists said the the effect could be explained by the unique properties of the bonds that hold water together.
Individual water molecules are brought into contact by hydrogen bonds, which causes natural repulsion and allows the bonds between oxygen atoms and hydrogen to expand and store energy.
When boiling water is placed above the man’s head, it forms a cloud in the atmosphere.
After being dropped into the freezing air, the boiling water becomes snow.
The hydrogen bonds are stretched as water molecules become further apart as the liquid cools.
Cooling occurs when the molecules are reduced again, and lose energy. Scientists believe that this explains why warm water cools quicker than cold.
Environment Canada issues an emergency warning about extreme cold in Alberta following a blast of Arctic Air that brought freezing temperatures to the area.
In Edmonton, temperatures of around -40C are expected to continue this week and in Calgary, the current forecast is predicting a wind chill of around –43C.
Environment Canada spokesperson Dave Phillips stated to CBC News, “Extremely cold, brutal cold. It is hard to put a name on it.”
David Feriheit (Canada, family blogger) used sub-zero temperatures for the 2018 Mpemba effect exploration.
Video footage showed that Mr. Freiheit threw a large bucket of boiling water in the air, before it became ice.
It took many attempts to make the video showing Mpemba’s effect in freezing temperatures (-28C) and it was finally completed.
He explained that he spent the day boiling huge quantities of water for lobster, then running to the lake to toss it around in the air. This was to create the Mpemba effect.
“I found the red dye I needed and, on my last effort to set the sun at night, Mpemba perfection.”
