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).

Webfreezing point, temperature at which a liquid becomes a solid. As with the melting point, increased pressure usually raises the freezing point. The freezing point is lower than the melting point in the case of mixtures and for certain organic compounds such as fats. Web3. Insert the small freezing point test tube into an 8-inch test tube (from your locker) with a cork (size #7) placed in between the two test tubes as shown in figure given below. The cork helps adsorbing the shock during stirring. The outer test tube serves as an air- jacket to prevent the solvent from cooling too quickly. 4. graphene in cement https://krellobottle.com
