Isn't the boiling point dependant on the pressure the liquid is under, since liquids boil when the tiny gas-bubbles that form all the time at random are pressurized enough to stay and grow, rather than being instantly crushed?

I guess I'd just look that up on a table or a PVT diagram.. I hear that you need a gigantic messy system of equations to approximate water's state transitions, and everyone just uses tables

Standard altitude table says that at 5900m:

p = 4.7867 E4 N/m^2

Consulting a Saturated Water-Pressure table for 50kPa (closest value) gives 81.33 degrees C as saturation temperature.

40kPa -> 75.87 C

You can interpolate back from there.
