While in a liquid state, an energy transfer to or from water heat changes the temperature.
So let's break up your question in two parts: But sprinkling salt on icy walkways won't help if the ambient temperature is below -21 degrees Celsius. If you add enough salt, the freezing point of water can be dropped as low as -21 degrees Celsius.
Retrieved February 27, 2019 from www. In most situations, a little bit of dust, impurity, or even little vibrations in the water provide nucleation centers for the water to freeze onto.
But any remaining liquid water can survive only an incredibly short time -- too short for the liquid's properties to be detected or measured. You can also check out this link for 'maximum freezing point depression NaCl' from a google search.
So generally no, any warmer and pure water will be all liquid, and vice versa. Fahrenheit's experiment was not done with seawater. Liquid water is a network of water molecules each with two hydrogen atoms and one oxygen atom held loosely together by what is called hydrogen bonding, which is somewhat like static cling.
Deziel, Chris. So, then what difference does adding salt make?
The temperature for formation of stable nuclei will also change depending on the presence of heterogeneous nucleation sites impurities in the water or container walls. You are asking two questions in one!
This is due to the partial negative charge on water and partial positive charge on hydrogen. Once freezing rain hits an object on earth's surface, that object provides nucleation centers, and the rain freezes to ice.
Since the extent of freezing-point depression - the number of degrees by which the freezing point of the solvent drops - depends on the concentration and nature of the solute, the freezing point of seawater is NOT uniform across different seas and oceans!

Perhaps if we knew a little more about why you're interested we'd be able to give you a more detailed answer if you'd like.Super Cooling Water (Freezing at Different Temperatures)
NOAA Regards,. At standard pressure, pure water can be supercooled to as low as about -40 degrees Celsius.
