Water is really abnormal substance since its thickness is reduced in its hard state 보다 its fluid state.
You are watching: What factors affect the density of ocean water
The thickness of water is 1kg/L(at 278.15K)
Density of ocean water likewise depends three factors
One is depth and air pressure, the various other one is salinity the water and also the other one is is temperature.
This graph mirrors the thickness with altitude. This graph is completely different for nearly all compounds because their thickness in the solid state is much more than its thickness in fluid state. So thickness decreases through the altitude.Low pressure additionally creates the gas come expand and lose energy which cause it to lose energy. In atoms power is actually warm which the loses.
You only require the initial volume that to calculate the expansion of water in higher temperature.
#DeltaV = betaV_
Where #DeltaV# is readjust in volume#beta# is a constant#V_
# is original volumeAfter you understand the volume density can be easily calculatedNow look in ~ this graph
You deserve to see the the air press decreases with increasing altitude.So density of water decreases through decreasing waiting pressure.
Effect that Salinity top top water
Now the impact of temperature on water
The graph is bent as when the water begins to freeze it looses density yet increases again in low temperature however not near 32F
But the result of warmth on "sea water" is small different
Because the water is evaporating and the salt is left which dissolves in the left water making it high concentration. This is as with heating a systems to gain a more concentrated solution.

But tho the price of evaporation is less reliable than the thermal expansion of water as such at high temperature also the s water is quiet at lower density.
And that is why the density increases with lowering temperature
