Why is sea water denser than air?
Water is heavier than air because it is DENSER. This means that more water molecules are packed into a given volume. Water density = 1,000 kilograms per cubic meter!!! The water molecule itself, H2O, is actually less massive than a Nitrogen molecule, N2, which makes up 80% of our air.
Which is more dense water or seawater?
Salt water is more dense than fresh water Seawater is more dense than fresh water so it sinks beneath freshwater. This means that when rivers flow out into the sea the river freshwater floats on top of the sea water.
What is density of sea water?
| Variable | Ocean Range | Ocean Mean |
|---|---|---|
| Temperature | -2°C to 40°C | 3.5°C |
| Absolute Salinity | 0 g/kg to 42 g/kg | 34.9 g/kg |
| Pressure | 0 dbar to 11000 dbar | 1850 dbar |
| In-situ Density | 1000 to 1060 kg/m3 | 1036 kg/m3 |
Which ocean is more dense?
The Pacific has most of the lightest water with densities below 26.0, whereas the Atlantic has most of the densest water between 27.5 and 28.0. Antarctic bottom water is indeed densest for Pacific and Indian oceans but not for the Atlantic which has a lot of similarly dense water.
Where is the most dense ocean water found?
Antarctica
What is the molality of pure water?
The density of pure water at room temperature i.e., 25∘C is 0.9970749 g/mol, therefore the mass will be 0.9970749 kg, and the molecular mass is 18.0148 g/mol. Moles=997.0749 g18.0148 g/mol=55.348. So, the molality will be: Molality=55.3480.9970749=55.510 m.
At what temperature does water has minimum density?
about 14°C
At what temp water has maximum density?
4 °C
Why is 4 degree water the most dense?
The molecules of the water are closer together, and this increases the density of the liquid. As the temperature of warm water decreases, the water molecules slow down and the density increases. At 4 °C, the clusters start forming. Thus, the density of water is a maximum at 4 °C.
What temperature of water has the least volume?
4 °C.
At what temp water has least volume and highest density?
The density of water is maximum at 4oC and hence its volume at this temperature is minimum.
At which temperature volume of water 💦 is maximum?
water has a maximum volume at 4 degree c and 1 atm .
