Sea water contains much more dissolved material like salt (The Pacific has more than 33 g NaCl per liter) and other stuff than river water does (<0.5 g/L).
Seawater does not have a density of 5.
No, an iceberg is approximately 10% less dense than seawater. This is why it floats

specific gravity means that the ratio between the density of pure water to the density of that material is ----- so the density of the water you are talking about is 1.0254966times the density of pure water which is one so the density of that type of water is 1.0254966 density = mass / volume 1.0254966 = mass / 28316.8 mass = 29038.78 gm = 29.038 kg the weight = m g = mass * 9.8 =284.58 N
The rate of dehydration is greater in seawater because seawater has a higher salt concentration compared to fresh lake water. When you drink seawater, the body has to work harder to eliminate the excess salt through urine, ultimately leading to more water loss and increased dehydration.
It is easier to float, in any case, because salt water has a greater density.
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 )
sea water is less denser than river water.
Sea water will provide more buoyant force than river water because seawater is denser due to its higher salinity. The higher density of seawater results in greater buoyant force acting on objects floating in it compared to river water.
The density of seawater is approximately 1030 kg/m3Note that:1. Density is a measure of the mass per unit volumeIt does not depend on the sample's size.2. The density of seawater is greater than that of fresh water which has a density of approximately 1000 kg/m33. The density of water varies with temperature and impurities.
Greater density
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
Seawater does not have a density of 5.
the salt makes seawater denser than freshwater. more salt increases the density
The density of the fresh water is less than the density of the salt water.
Processes that increase the density of seawater include evaporation, which removes water and concentrates the salt content. This increased salinity makes the water denser. Other processes that can increase seawater density include cooling and the formation of sea ice.
