Can ice water be colder than 0 degrees Celsius?

Question

I am in 7th grade and this is all confusing to me. no lectures please, simple and short. also, there is NO salt is the water. Just plain old water and ice. boom. ice water. NO SALT!!! thank you!

Answer 1

Yes. With enough pressure or with salt it can stay fluid to well below zero.

Answer 2

Yes, when it contains salt. Remember how you put salt in water to get it to boil faster, or put rock salt in an ice cream freezer? That's because adding salt changes the freezing point AND boiling point of plain water. That's why, when you read about the Titanic victims being in water below 32 degrees F - it was ocean water - or salt water. Same with the ice cream maker, the salt lets the water outside the ice cream tank get colder than freezing and still stay liquid. Cool, huh??

Answer 3

With the conditions that would normally be assumed (pure water, pressure of 1 atmosphere) no. At 0 degress Celsius water becomes ice.

However, with the addition of something to the water (such as salt) or a higher pressure, water can stay liquid at below that temperature.

Answer 4

At high pressure or with something mixed into it, like salt, it can stay a liquid below 0 Celsius.

Answer 5

Salt Water (at which point would no longer be PLAIN PLAIN WATER h2O ICE) does freeze at a lower temp than plain water. Water with 23.3% salt (by weight) will freeze at -21.1 degrees Celcius.

Answer 6

Pure water can stay liquid if under pressure even colder than 0 degrees

Also if you add salt it can go much colder

Answer 7

If ice water gets colder than 0 deg celsius it will freeze into ice. So my answer will be no because it will no longer be ice water, it will be ice.

Answer 8

YES DEPENDING ON THE AMOUNT OF SALT IN IT IT CAN GET WELL BELOW FREEZING.

Answer 9

nope, it would be ice then.
