Triple Point of Water

Follow by Email
The triple point occurs where the solid, liquid, and gas transition curves meet. The triple point is the only condition in which all three phases can coexist, and is unique for every material. Water reaches its triple point at just above freezing (0.1° C) and at a pressure of 0.006 atm.


Ivan Pagnossin : Very nice! Thanks :D However, a little typo: triple point occurs at 0.01 °C (273.16 K), not 0.1 °C.

C Smith : That's crazy, science is cool.

Terran123rd : Imgur says hi.

Noah Nicholes : At a moment like this I am reminded how the basic understanding of scientific fundamentals is heavily influenced by constant variables that are present due to the natural and chaotic elements of life. only in a chaos free enviornment can water boil, freeze, and melt at the same time. I see, but I do not understand.

Yash Permalla : Wait so does the triple point only work in vacuums? I’m confused

SaltyStorm : that is very cool

John Daker : I'm confused. I understand the freezing, but where is the heat source to cause the boiling? If the temp is 0.1 degree Celsius, how is it boiling? And if it's boiling, there seems to be no steam. Without steam, there is no gas.

INTRO Sting : This is a very dangerous we did it in class in the 8th grade and Timmys dad beat him with jumper cable wires

Deanzphx Gaming Channel : Very nice!

lisarenee3505 : Scientists can science, but apparently they can't grammar very well. _"Ice water is placed inside a vacuum chamber and turned on to lower the pressure."_ Umm... how do you "turn on" ice water (because that's what it says) and what does that have to do with lowering the air pressure? /sarcasm
