because it has a higher concentration of ions and minerals!!!
ions and minerals play a vital role to make sea water more dense.
secondly, the molecular mass:
water: h(2) + o(16) = 18g/mol
NaCl = n(23) + cl(35.5) = 58.5g/mol
NaCl has a higher moleculer mass so there is higher density than water seen!
What else can I help you with?
Which has greater density ice or water how can you say that?
Water has a greater density than ice.
Why do high latitude water lack a pycnocline?
Density variations of seawater with latitude are very similar to those for temperature variations with latitude. Because of the influence of temperature on seawater density, low latitudes exhibit lower densities at the surface that rapidly increase with depth. Higher latitudes exhibit little or no difference in density owing to the lack of a thermocline. Such a rapid change in density with depth is called a pycnocline, and like a thermocline is absent at higher latitudes.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
If an object 's density is greater than the density of a fluid it?
It will sink in the fluid. It will sink in the fluid.
Why it is easy to swim in a swimming pool than river?
In a river,flowing water exerts a force on the swimmer. To cross the river or to swim upstream the swimmer has to overcome this resistive force. This requires spending a lot of energy. As there is no flow of water in a swimming pool, the swimmer does not have to overcome the resistive force as in river. Hence it is easier to swim in swimming pool than in a river.
What is the density of wood in ocean and freshwater?
It is 787.975 in seawater and freshwater's is 211.
If freshwater and seawater meet at the mouth of a river which one sinks and why?
Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater
What is the scientific difference between seawater and freshwater?
Seawater has a higher concentration of salts and minerals compared to freshwater. Seawater also has a higher density and freezes at lower temperatures than freshwater. Additionally, seawater has a higher pH and different composition of dissolved gases compared to freshwater.
Does salt content of water affect the density of seawater?
the salt makes seawater denser than freshwater. more salt increases the density
Does freshwater or saltwater have a greater density?
Salt water has a greater density.
Seawater is different to freshwater because it contain?
higher levels of salt and other minerals, making it more saline than freshwater. Seawater also has different organisms and ecosystems adapted to its unique conditions compared to freshwater environments. Additionally, seawater has a higher density and freezing point compared to freshwater.
What makes seawater denser?
Seawater is denser than freshwater because it contains salt. The salt in seawater increases the mass of the water without significantly increasing its volume, making it denser. Temperature and pressure can also affect the density of seawater.
Which object will sink in freshwater which has a desity of 1.0 gcm3?
Any object with a density greater than 1.0 gmcm3.
Processes that increase the density of seawater include evaporation and .?
Processes that increase the density of seawater include evaporation and the freezing of seawater into sea ice. Evaporation causes the water volume to decrease while the salinity stays the same, increasing density. Sea ice formation removes freshwater, leaving behind denser saltwater.
Why does seawater have a greater buoyant force than fresh water?
Seawater has a greater buoyant force than fresh water because seawater has a higher density than fresh water therefore the buoyancy is higher. *Improved* This happens because when water mixes with the salt in sea water, the density changes to the average density which is around 1.55 g/mL (Average density is the density of different materials put to together )
Is bluefish a freshwater animal or a seawater animal?
its a seawater fish
Why is pressure 500 feet under the ocean greater than the pressure 500 feet under the great lakes?
The pressure under the ocean is greater than under the Great Lakes because the density of seawater is higher than freshwater. Seawater is also influenced by the weight of the water column above due to the depth of the ocean, leading to higher pressure.
