(49g) (50g) Water boiling temperature = f(altitude/pressure + temp); Water density

[Gil]

Boiling temperature (of water)
=f(pression), without inclusion of air.Temp.
See:
https://www.omnicalculator.com/chemistry...t-altitude


But pression =g(altitude, air.Temp), so that
Boiling temperature (of water)
=f(altitude, air.Temp).
See:
https://planetcalc.com/275/

Greater pression —> Higher boiling temperature.

Greater local temperature —> higher pression —> Higher boiling temperature.

A must, therefore, to calculate "more or less accurately" boiling temperature is to have both altitude and local temperature, in order to get first the pression, which enables then to reckon the local estimated boiling temperature.

Another way is to introduce directly the effective measured pression at Altitude h, as suggested in the second reference given above.

Note that g is taken as a constant, which is not absolutely true.

So that the final result is more an indication.
Degree of accuracy is beyond my scope, perhaps 1/10 or 1/100 of Celcius degree?

I included the references in the new version.
