What else can I help you with?
Is sea water the same as water?
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
Does sea water has a higher density than pure water?
Yes, sea water has a higher density than pure water due to the presence of dissolved salts and minerals. The higher density of sea water allows objects to float more easily in it compared to pure water.
What property causes an object to float in salt waterr but sink in fresh water?
The property that causes an object to float in saltwater but sink in freshwater is density. Saltwater is denser than freshwater due to the dissolved salts, so objects that are less dense than saltwater will float in it but sink in freshwater.
Why is the sea water and freshwater pH different?
The pH of seawater is typically higher than freshwater due to the presence of minerals and salts, which can buffer against changes in acidity. Freshwater bodies are more vulnerable to changes in pH because they lack these buffering compounds. Human activities such as pollution and acid rain can also contribute to fluctuations in freshwater pH.
Processes that increase the density of sea water included evaporation and what?
Water being evaporated, the concentration of salt increase and as a consuquence the density increase.
Why can we float easier in the sea than in a freshwater lake?
The density of salt water is higher than fresh water.
Is sea water the same as water?
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
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.
Does sea water has a higher density than pure water?
Yes, sea water has a higher density than pure water due to the presence of dissolved salts and minerals. The higher density of sea water allows objects to float more easily in it compared to pure water.
Why is it easier to float in the sea than the swimming pool?
It is easier to float in the sea because the saltwater is denser than freshwater in a swimming pool, providing more buoyancy. Additionally, the saltwater's buoyant force helps you float more effortlessly compared to freshwater.
How does pressure change the density of sea water?
Pressure increases the density of sea water because it compresses the water molecules closer together, reducing the volume occupied by the same amount of water. As pressure increases with depth in the ocean, the density of sea water also increases. This effect is known as compressibility.
How does the pressure at a certain depth in sea water differ from that at the same depth in river water?
Since liquid pressure is function of density,acceleration due to gravity and depth of liquid level so here density of sea water is greater than that of river water ,so liquid pressure in sea must be more.
Why seawater has greater density then that of freshwater?
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!
Is there sea water in the swan river?
The river is freshwater
What property causes an object to float in salt waterr but sink in fresh water?
The property that causes an object to float in saltwater but sink in freshwater is density. Saltwater is denser than freshwater due to the dissolved salts, so objects that are less dense than saltwater will float in it but sink in freshwater.
What is the difference from a lake vs sea?
A lake has freshwater and the sea has salt water.
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
