High vs low freezing point
WebFeb 11, 2024 · Cars operate in a wide variety of temperatures, from well below freezing to well over 100 F (38 C). So whatever fluid is used to cool the engine has to have a very low freezing point, a high boiling point, and it has to have the capacity to hold a lot of heat.. Water is one of the most effective fluids for holding heat, but water freezes at too high a … WebFeb 2, 2024 · Because the freezing point of pure water is 0°C, the actual freezing points of the solutions are −22°C and −30°C, respectively.

WebDec 9, 2013 · As you add more salt to water, its freezing point continues to drop until the water reaches saturation and cannot hold any more salt. If you add enough salt, the freezing point of water can be dropped as low as -21 degrees Celsius. This fact means that water at -21 degrees Celsius can still remain liquid if enough salt is added. WebAbove the freezing altitude, the temperature of the air is below freezing. Below it, the temperature is above freezing. The profile of this frontier, and its variations, are studied in meteorology, and are used for a variety of …
