Ice. It expands when it's 0 degrees Celsius.
Ice is less dense than water at a temperature of 4 degrees Celsius. This is because the hydrogen bonds in water cause the molecules to be more spread out and less tightly packed compared to when it is in a solid state as ice.
The lowest density in water occurs at 4 degrees Celsius, where water is most dense. As water cools below or heats above this temperature, its density decreases, causing it to expand and become less dense.
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.
9 degrees less than 0 degrees Celsius is -9 degrees Celsius.
9 degrees less than 2 degrees Celsius would be -7 degrees Celsius.
More dense than what? I presume you mean is it more dense at that temperature than at lower temperatures. The answer is no, it gets denser at lower temperatures, all the way down to 4 degrees centigrade. Then it gets less dense again.
It's at its most dense at 4 degrees Celsius. Below that it becomes less dense until it freezes and above 4 degrees Celsius it also gets progressively less dense (due to its expansion).
The density of pure water at 97 degrees Celsius is approximately 0.971 grams per cubic centimeter. At this temperature, water is less dense compared to at 4 degrees Celsius (which is the temperature at which water has its highest density).
ANSWER At 4 degrees Celsius. This is the temperature at which specific gravity is defined. Note that ice floats because it is less dense than the water it is in. Water is the only substance known which is less dense as a solid than as a liquid.
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.
Ice is less dense than water at a temperature of 4 degrees Celsius. This is because the hydrogen bonds in water cause the molecules to be more spread out and less tightly packed compared to when it is in a solid state as ice.
Water expands at 4 degrees Celsius because this is the temperature at which it reaches its maximum density. As water cools below 4 degrees Celsius, it begins to expand and become less dense, eventually transforming into ice. This unique property of water is due to the hydrogen bonding between water molecules.

at -4 degrees celsius if the water is a solid state of matter,it will turn into a liquid
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.
At Zero degree Celsius.(or less)
