The maximum density of water is around 4° Celsius. What is the maximum density of water?Īns. Density is usually denoted using the symbol ρ, so the formula for density is: ρ = m / V. How to Calculate the density of Water Formula?Īns. The density of seawater can be increased by reducing its temperature, increasing its salinity, or increasing the pressure. 1 g/cm 3 at 4o C is the density of freshwater, but the addition of salts and other dissolved substances increases surface seawater density to between 1.02 and 1.03 g/cm 3. Water has a density at 250 Celsius of 997 kg/m 3. Check out the Density Vs Temperature graph mentioned below to understand how density changes with temperature.ĭensity of Water at Various Temperature ScalesĪns. Water has a higher density in the liquid state than the solid. Water does not have absolute density as its density varies with temperature. This type of unusual negative thermal expansion is related to strong intermolecular forces, dependent on orientation or interactions, and is observed in the form of molten silica. It is temperature-dependent, but this relationship is said to be non-linear and unimodal rather than monotonic.Īs it cools from room temperature, liquid water tends to become more and more dense, like other substances, but at about 4 ☌ pure water reaches its maximum density.Īs it cools further, it tends to expand and become less dense. The density of water is approximately 1 g/cm3 (1 g/cm 3). Some of the factors that affect the density of water are given in the points below. Many factors can affect the density of a substance. On the other hand, when the pressure decreases, the molecules move apart. As the pressure increases, the molecules of the substance are brought closer together, resulting in a higher density. Effect of Pressure on Densityĭensity increases as pressure increases and decreases as pressure decreases. At sea level, the density is about 1027 kg/m 3. Seawater has salt and minerals that make it denser than normal water. At room temperature, water remains in a liquid state. The density of water at 250 Celsius is 997 kg/m 3. At room temperature (~200C), its value is 998.2 kg/m 3. Density of Water At Room TemperatureĪ density of water is defined similarly to other substances. The density of a substance or material can be defined as the relationship between the volume it occupies and the mass of a substance. It is a measure of how tightly the mass is packed together. The Material density is defined as its weight per unit volume. Density of several liquids with different specific gravity.
