does water boil quicker at higher elevations?

207 views

I read a couple articles that talk about the different temperature requirement at different elevations, but does this change the time required to boil said pot of water? if the temperature to boil the pot of water i’m assuming the time to boil it will also be lower? but perhaps the air pressure changes something that i’m not aware of

also chemistry? is that the right flair? sorry if it’s not

Water will boil at a a lower temperature at a lower pressure. That’s the diagonal line on the phase diagram. Earth’s atmospheric pressure drops as you go higher in elevation.

A vacuum pump can be used to take advantage of this: https://en.wikipedia.org/wiki/Vacuum_drying and https://en.wikipedia.org/wiki/Freeze_drying

The time required to boil does require the assumption that the amount of heat per time is the same. However, a gas-air fire at altitude will have less air, so gas flow has to be reduced: https://www.reddit.com/r/Cooking/comments/v5cojr/are_gas_cooktops_at_high_elevation_less_effective/
