As you can see in the chart, water only has an exact density of 1 g/cm 3 at 39.2°F or 4.0°C. Once you get below water's freezing point (32°F/0°C), the density of water decreases because ice is less dense than water.
Seawater density is typically slightly higher than the density of pure water, about 1.02g/cm 3 to 1.03g/cm 3. Below is a chart that shows the density of water (in grams/cm 3) at different temperatures, ranging from below water's freezing point (-22°F/-30°C) to its boiling point (212°F/100°C).
Water’s density changes depending on the temperature, so if you’re doing an experiment close to or past water’s boiling or freezing point, you’ll need to use a different value to take into account the change in density. Both steam and ice are less dense than water.

An important property of water is its ability to act as a good solvent. This could best be explained by water's. air moving from a large body of land to a large body of water. Convergence resulting in rising atmospheric motion at the surface can occur in all of the following settings EXCEPT.
at the subtropics because descending air promotes clear skies.
westward moving winds weaken causing the mound of warm water in the western Pacific to move eastward.
Cold dense air sinks at the poles, flows outward away from poles, and rises between 60 and 45 degrees latitude .
Urban areas heat up more rapidly than surrounding countryside. This can result in

as one moves up in the atmosphere, pressure decreases , as one moves closer to the earth’s surface, pressure increases
Coriolis deflection causes warmer surface waters to deflect to the northwest causing deeper, cooler waters to replace the dispersing surface water.
Geographic factors are important when considering environmental issues or when evaluating potential sites for a new agricultural area or business because

Density is the mass per unit volume of a substance. The density of water is most given as 1 g/cm3, but below is the density of water with different units.
You can find the density of any substance by dividing its mass by its volume. The formula for density is: ρ=m/v, with density represented by the symbol ρ (pronounced "rho").
Calculating the Density of a Liquid With a Hydrometer. If you're trying to calculate the density of a liquid, you also can do so by using an instrument known as a hydrometer. A hydrometer looks like a thermometer with a large bulb at one end to make it float.
So if you had a different, irregular piece of aluminum that weighed 550g and displaced 204mL of water in a graduated cylinder, then your equation would be ρ = 550g/204mL = 2.7g/mL.
So, 1g/1cm 3 = 1 g/cm 3 , giving water its easy-to-remember density. However, water's exact density depends on both the air pressure and the temperature of the area. These variations in density are very slight though, so unless you need to know very exact calculations or the experiment takes place in an area with an extreme temperature/pressure, you can continue to use 1 g/cm 3 for water density. You can look at the chart in the next section to see how water's density changes with temperature.
Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, which means a cubic centimeter (1cm 3) of water weighs one gram (1g).
Below is a chart that shows the density of water (in grams/cm 3) at different temperatures, ranging from below water's freezing point (-22°F/-30°C) to its boiling point (212°F/100°C).
