Allergy Headache Management and Treatment. 1  For all headaches, identify triggers and avoid them. 2  For relief of sinus headaches, make changes to your home and to your behavior. 3  Control some headaches with nonprescription (over-the-counter) medications.  See an allergist for prescription medications, which may be more effective.
At temperatures below 32 Â° F (0 Â° C), liquid water freezes; 32 Â° F (0 Â° C) is the freezing point of water. At temperatures above 32 Â° F (0 Â° C), pure water ice melts and changes state from a solid to a liquid (water); 32 Â° F (0 Â° C) is the melting point.
PG freezes at around -12C/10F and VG at around -17C/1.4F. If you plan to be out in extreme cold for an extended period of time, mixing a little bit of distilled water in with the juice would significantly lower the freeze point as the water acts as an anti crystallization agent. 10% water would lower the freeze point to -29C/-20F and the lowest would be at 30% water content where the freeze temp would be -51C/-60F. Freezing would have no detrimental effects on the juice other than the need for it to have to warm back up to room temperature before being able to use it again. The big concern with it freezing inside a full tank would be expansion and possible cracking.
