airfoilmod,
...I still dont follow you.
... Fall in pressure is accompanied by a fall in boiling point and an increase in evaporation (or even gassing) ,I presume youve made tea in the galley at 8000ft cabin alt?
...When you open the soda bottle, pressure drops sharply and the gas expands , temperature goes down, producing sufficient drop in the water to freeze it into ice slush .But dont tell me we suddenly find the freezing point of the water going up
....No ,the bottle temp goes down.Try it with the CO2 bottle ! Or the choke of my Rotax carburetter
