Density of Water: Does Cooling Below 0°C Affect It?

In summary, the density of water at 0°C is 1 gram per cubic centimeter. As the temperature increases, the density decreases and as the temperature decreases, the density increases due to the expansion and contraction of water molecules. Water reaches its maximum density at 4°C, meaning the molecules are closest together and the water is most compact. When cooled below 0°C, water freezes and the density decreases even further. Under certain conditions, such as high pressure or dissolved substances, water can have a density greater than 1 gram per cubic centimeter. However, at standard atmospheric pressure, the maximum density of water is 1 gram per cubic centimeter at 4°C.

we know that density of water is maximum at 3.98°C but when it is cooled below 0°C, will its density decrease by decreasing temperature and will there be a temperature at which its will be higher than that at 3.98°C...?

the density of water is maximum at 3.98°C... so that clearly states that there can be no other temperature at which the density will be more than that! and yeah it's density will decrease if you decrease (or increase) temperature. but then again, water will freeze at 0°C, unless you regulate the pressure accordingly.
 

What is the density of water at 0°C?

The density of water at 0°C is 1 gram per cubic centimeter.

How does the density of water change with temperature?

The density of water decreases as the temperature increases, and increases as the temperature decreases. This is due to the expansion and contraction of water molecules as the temperature changes.

At what temperature does water reach its maximum density?

Water reaches its maximum density at 4°C. This means that at this temperature, the water molecules are closest together and the water is most compact.

What happens to the density of water when it is cooled below 0°C?

When water is cooled below 0°C, it starts to freeze and form ice. This causes the density of water to decrease even further, as the molecules spread out and form a crystalline structure.

Can water have a density greater than 1 gram per cubic centimeter?

Yes, under certain conditions, water can have a density greater than 1 gram per cubic centimeter. This can occur at very high pressures or when certain substances are dissolved in the water, such as salt. However, at standard atmospheric pressure, the maximum density of water is 1 gram per cubic centimeter at 4°C.
