If you decrease the pressure, the freezing point of water will increase ever so slightly. From 0° C at 1 atm pressure it will increase up to 0.01° C at 0.006 atm. This is the triple point of water. At pressures below this, water will never be liquid. It will change directly between solid and gas phase (sublimation). react header footer layoutWebWater actually boils at a lower temperature if the pressure around it is lowered. This is why if you go to a high altitude location (like many parts of New Mexico), where the atmospheric pressure is lower, water will boil at slightly less than 100 degrees C.
