What is the freezing point of drinking water?

[Vivaldi]

It doesn't freeze at minus 3-4 degree temperatures.

At least not in a bottle or glass.

Or does it take for days to freeze?

Closed or open bottle. Open, it's 32F/0C. Closed, you start having to account for pressure inside the bottle. Liquid water has been found at negative 40F in clouds and replicated in a lab, but that's under strict environmental control. If you're talking about popping a bottle out on a cold day, then 32 degrees +/- a degree or so provided you're not at some elevation extreme. Takes about an hour or two to freeze for me in the winter, but on cold day's I've had it freeze in 10 minutes, depending on the size of the bottle. The residual heat contained IN the bottle has to work it's way out, so a 50ml bottle will freeze much faster than a 4L bottle provided they came from the same tap. Then obviously the temperature of the tap it came out of would matter.

At minus 4 it should be freezing under most uncontrolled conditions if left for any significant length of time. Sure your thermometer is correct?

Drinking water is not pure water.

It does not freeze at -4°C no matter how long it stays.

[Vivaldi]

Yes, I am sure.

[Vivaldi]

Tried at -3°C, it didn't freeze.

Tried at -4°C, it didn't freeze.

All drinking water is not the same. Depends on what your municipality is pumping into it. Mine personally freezes at -1C and some change if I drip it before the house filter, but closer to zero afterwards. What is your freezer set to? It freezes there, would be interesting to see at which point you'd have to back it down before it does.

[Vivaldi]

Did you try it to freeze at -1°C?

[BoopBoopBeep]

Not just now... i have before... thats how i knew the difference between before and after my water filter

0. It will just take a long time to freeze at that temp and likely never will if it’s disturbed

What's the car in your profile picture?

0 Celsius or 32 F.

I am saying drinking water.

Not pure water.

Drinking water.

[Vivaldi]

I can't feeze the drinking water at minus 3-4 degrees in a bottle or a glass.

It does not freeze.

It needed well below zero to freeze.

[jahaims]

Volume, starting temperature, etc, are all variables that will change how long it takes. Tap water will freeze at 32f.

[Vivaldi]

No matter what temp I start, I can't freeze the drinking water at minus 3-4 degrees in a bottle or a glass.

It seems it will stay liquid indefinetly.

[Vivaldi]

*indefinitely*

[Vivaldi]

Also as far as I am consired.

For pure water to freeze, the air temp should be below the freezing point of it.

And drinking water has lower freezing point than pure water

[Anonymous]

32 F.

Drinking water is not pure. It must have a lower freezing point.
