The freezing point of water decreases as the pressure decreases in a partial vacuum. At standard atmospheric pressure (1 atm), water freezes at 0°C (32°F). However, at reduced pressures, water can remain in a liquid state at temperatures below 0°C due to the lower pressure affecting its freezing point.

What temp will spit freeze when it hits the ground?

Spit can freeze instantly upon hitting a surface if the temperature is below 32°F (0°C). However, factors like wind chill and humidity can affect how quickly this happens. Generally, freezing can occur at or below the freezing point of water.


What temp does flowing water freeze?

Yes, but not at standard pressure. Assuming that the 0 degrees refers to Celsius, the water will begin to freeze at 0 if pressure is standard. Assuming that the 0 degrees is Fahrenheit, the water has already frozen by the time we reach 0.However, if pressure is increased, this will tend to force ice to melt regardless of the lower-than-normal-freezing-temperature. This is because liquid water is denser than ice and increasing pressure favors denser forms of matter. (It is important to note that this is a unique trait of water. Most chemicals have an increased density in their solid state.)


If you have water at 32 degrees and ice at 32 degrees and you put them together will the ice melt or the water freez?

If you have water and ice at 32 degree Fahrenheit, their state will depend upon the temp. of the surroundings. If it is >=0 then ice will remain such but water will start to freeze. If it is <0, then the ice will melt and water will remain as such. The first condition is true only if heat isn't being supplied the system at zero degree celsius.


How do I undo a vacuum between a glass bowl and a glass dish without breaking either-the dish is stuck in the bowl on top of food?

You can try to break the seal between the glass bowl and dish by gently tapping the edge of the bowl with a wooden spoon or rubber mallet. Alternatively, you can try running hot water over the outside of the glass bowl to help expand it slightly and release the vacuum seal. Be careful not to use excessive force to prevent breakage.


Does the amount of water affect its temp?

No, the amount of water does not affect its temperature. The temperature of water is determined by the amount of heat energy it contains, regardless of the quantity of water present.
