This Water Gets COLDER when it Boils!

[@Doubleolseven]

When you decrease the pressure slightly below saturated vapour (the water vapours that float freely above water surface, with no need to turn into liquid or disperse), the liquid water temperature doesn’t change, meaning there is enough heat in the liquid to boil. Water vapours are colder than water liquid and the process continues until the temperature in the remaining liquid matches the temperature of saturated vapours, or the entire liquid evaporated. If liquid water was already colder than vapour state, then the water is in the process of solidifying, so reducing the pressure further will also reduce the vapour state pressure and since there is not enough heat to boil the entire volume of liquid, the remaining liquid turns into a block of ice.

Enjoyed it. Thank you.

Nice video sir. Keep it up ❤.

Thank you, I will

Really cool presentation. Thank you!

Nice 👍

This is exactly what happens with a freon in an evaporator used in air conditioning. The liquid freon flashes in the evaporator changing from a liquid to a gas and absorbs heat energy to accomplish this which cools and dehumidifies the air.

Спасибо!

Thank you very much!

So we can decrease the temperature of water(here), by lowering the pressure. And finally when it does not boil, actually at that point the temperature is lower than the boiling point.😊

What the hell is going on here?! :D
