Snow and Ice
Does ice expand at -4 degrees Celsius?
Yes. Frozen ice is less dense than liquid water. That is why ice
cubes float in your drink!
In fact at positive 4 °C, water is the most dense. Colder than
that, and the density decreases, and also warmer than that, the

Is it - 4 degrees Celsius is water freezing point?
Asked in Chemistry
When water at 4 degrees Celsius is cooled it does it contract?
Asked in Science
What is waters reaction to heat?
Water has three states Solid (ice) liquid (water) gas (steam) When water is heated it expands and when it is cooled it contracts until about 4 degrees Celsius when it begins to expand again. So the answer to your question is it depends on what temperature the water is. If it is a liquid and over 4 degrees then it will expand. If it is not frozen but somewhere between 0 and 4 degrees it will contract until about 4 degrees and then expand. Under 0 degrees it is ice not water, over 100 degrees it is steam not water.
