WebFeb 13, 2024 · Coolant is a 50/50 mix of antifreeze and water for the best balance between a low freezing point and high boiling point. If you're tempted to use 100% antifreeze for super mega protection against the cold, think again. Pure coolant has a freezing point of 0 degrees Fahrenheit—not nearly as efficient as -35! 5. WebThere are two ways that the higher pressure lowers the freezing temperature. One is direct. Ice occupies more volume than liquid water, so squeezing harder favors the liquid over the ice state. The second is less direct. At higher pressure, more air (nitrogen and oxygen molecules) goes into solution. Web8 years ago.
