Temperature and Salinity. Both are important although temperature has a much greater effect than salinity on seawater density.

What is d density of normal water?
Generally, barring unusual temperatures / pressures the density of water is 1 g / mL The density of water at sea level pressure and 4C temperature is exactly 1 g/mL, at different temperatures it is always less. At different pressures things become more complicated.
How can you find the conclusion for how salty does the sea have to be for an egg to float?
yes i proved my hypothesis correct. for my experiment to be correct it relied heavily on the density of the salt in the water
Is water less dense than the human body?
The average human body has a density of 1.010 kg/litreThe density of pure water is exactly 1 kg/litreThe density of sea water is 1.025 kg/litreSo the average human is denser than fresh water but less dense than seawater.There are significant differences in density between people, women tend to be less dense than men, muscular people tend to be more dense, fat people tend to be less dense. We can also reduce our density by breathing in deeply.Incidentally dead bodies tend to float after a few days due to the build up of decomposition gases within the body reducing its density.SourcesDensity of human body - http://en.wikipedia.org/wiki/Orders_of_magnitude_(density)Density of sea water - http://en.wikipedia.org/wiki/Sea_water
Density of fresh water?
This depends greatly upon the temperature the water. At 4oC the density is approximately 1000 kg/m3 (or 1 g/cm3) - more acurately though the density would be 999.97 kg/m3 (or 0.9997 g/cm3). Values for the density of pure water (H2O) have been calculated over a wide range of temperatures. At room temperature (22oC) The density of water is 997.77 kg/m3 (or 0.99777 g/cm3)
Why does an egg sink in fresh water but float in salt water but stays in the middle when pour water into salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.
What physical properties does water have in it?
Some physical properties include density, boiling point, and melting point. At 4 oC, the density of water is 1.00g/cm3. At sea level, water's boiling point is 100 oC and its melting point is 0 oC.
In general he density of sea water increases as?
depth and salinity increases density of sea water increases
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
Why sea water and freshwater do not have same density?
Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water
Why do ship float better at sea than in fresh water?
Sea water has salt, and therefore a higher density.
Why can you float in sea water easier than freash water?
sea water has a higher density
How does the density of water change with depth?
the density of sea increases with depth
What is the density of water at sea level?
At sea level, fresh water has a density of 1. 0 grams per milliliter. Seawater has a higher density than fresh water, 1. 025 g/ml.
What makes the sea water have density?
The sea water is so dense because of all of the whale sperm in the sea.
Where would the lowest density of sea water be found?
the dead sea
Does sea water has a higher density than pure water?
Sea salt and table salt are made of the same chemical compound. They have the same density. Sea salt is slightly less refined than table salt and may contained more minerals.
What is the density of the water the sea lions live in?
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
