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 density decreases.

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 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.

What happens to water molecules when temperature changes from 20 to -20 c?

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.

Why does ice melt at 4 degrees centigrade?

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.
