When can liquid water remain above 100°C?

Question

anonymous · Answer

when the pressure on it is greater than the pressure found at average sea level.

What the heck? 

Look at the triple point of water. You want to keep a constant pressure as you increase the temperature. So the pressure has to be the same at sea level or even lower. I dont know if you ever boiled water at a high elevation. Since its higher than sea level, the pressure is greater, and water boils lower in high elevation than at sea level.

anonymous · Answer

@jeyde205, you are correct, and @oOKawaiiOo, you seem to have misspoken.  Water will boil above 100C at *higher* pressures, not lower.  And when you go to higher altitude, the pressure becomes lower -- and this is why the boiling point falls.   @oOKawaiiOo, perhaps you meant to write that?

@Carl_Pham perhaps

Yes. I have misspoken. Good catch
