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?
Is easier to float in sea water than in fresh water?
Yes, it is easier to float in seawater than in freshwater due to the higher salt concentration in seawater, which increases its density. This increased density provides greater buoyancy, allowing objects, including a person, to float more easily. In contrast, freshwater has a lower density, resulting in less buoyancy and making it more challenging to float.
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.
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
How do you compare and contrast the density of seawater in the Mississippi River and the Mediterranean Sea?
The density of seawater in the Mediterranean Sea is generally higher than that of freshwater in the Mississippi River due to its salt content, which increases the mass of the water without significantly increasing its volume. Seawater typically has a density of about 1.025 g/cm³, while the density of freshwater in the Mississippi River is around 1.000 g/cm³. Additionally, factors like temperature and salinity variations can affect the density in both bodies of water, but the Mediterranean's saline nature consistently results in greater density compared to the freshwater of the Mississippi River.
Does freshwater or saltwater have a greater density?
Salt water has a greater density.
Is easier to float in sea water than in fresh water?
Yes, it is easier to float in seawater than in freshwater due to the higher salt concentration in seawater, which increases its density. This increased density provides greater buoyancy, allowing objects, including a person, to float more easily. In contrast, freshwater has a lower density, resulting in less buoyancy and making it more challenging to float.
What is density of seawater and freshwater?
The density of seawater typically ranges from about 1.020 to 1.030 grams per cubic centimeter (g/cm³), influenced by factors such as salinity and temperature. In contrast, the density of freshwater is approximately 1.000 g/cm³ at 4°C. The higher density of seawater is primarily due to its salt content, which increases its mass without significantly changing its volume.
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.
Which is more dense cold freshwater or warm seawater explain?
Cold freshwater is generally denser than warm seawater. As water cools, it becomes denser until it reaches about 4°C; below this temperature, it begins to expand and lose density. In contrast, seawater, while denser than freshwater due to its salt content, is typically warmer and less dense than cold freshwater. Therefore, cold freshwater is denser than warm seawater.
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.
