Ice melts at 0 degrees Celsius. That is a speciality of water.
At 3.98 degrees Celsius, the density of water is highest before it begins to form ice crystals. Water at this temperature may be a slush of water and ice.

How cold for how long will it take for just water to freeze in a car?
Ok, this is based on equations 0 degrees Celsius is freezing and water will freeze at zero Celsius, but the time to freeze in direct relationship to volume so depending on your vehicle it would take anywhere to 4-6 hours at zero degrees Celsius. For every degree below 5:1 ratio -1 degrees Celsius the 2.5-4.75 hours to freeze. At -20 1 hour or less, to crack the block 2-3 hours. -40 degrees Celsius would take 22 min to freeze and to crack the block 1:10.
When water at 4 degrees Celsius is cooled it does it contract?
No. When water is cooled it contracts up to 4 degrees Celsius and then it begins to expand till 0 degrees Celsius. This is called the anomalous expansion of water.
What happens to water at minus 20 degrees?
Water freezes and becomes ice at zero degrees Celsius. Also, water has the odd quality that it begins to expand below about 4 degrees Celsius. So the answer is that it would turn into ice and its volume would increase a little.
Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
no. The density changes
6 kg of water at a temperature of 90 degrees Celsius is mixed with 4 kg of water with a temperature of 22 degrees Celsius. What is the final temperature of the mixture?
THE ANSWER IS 62.8 DEGREES.....
How long does it take to freeze 4 cups of water at 17 degrees Celsius?
You can't freeze water at 17 degrees Celsius. The freezing point of water is 0 degrees Celsius or 32 degrees Fahrenheit.
Why surface of water freeze at 0 but under water not freeze even at 4c?
Because 4 degrees Celsius is higher than 0 degrees Celsius

Is it - 4 degrees Celsius is water freezing point?
ice crystals start to form at 4 degrees Celsius
What water temperature of Gulf Mexico is?
At that depth, pressure is the dominant variable in the Ideal Gas Law. And since Water has to expand to freeze, it stays around 4 degrees Celsius.
What temperature does pure water reach maximum density?
4 degrees Celsius
How cold is water under ice?
4 degrees Celsius
Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
no. The density changes
How much heat is needed to raise kg of water from 4 degrees Celsius to 83 degrees Celsius?
2,641,760J...

How can water float on water?
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).
