What is the gravity of salt water?

3- At what specific gravity of salt water does salt start to precipitate?

Salt starts to precipitate out of seawater at a specific gravity of around 1.17. This can vary depending on factors such as temperature and the type of salt.

How and why does salt keep water cold?

when salt dissolves in water it doesn't allow the water to get warm because it traps the heat within the water, therefore keepin the water cold. ...and a little thing called specific gravity comes into play....the water with specific gravity of 1 is now salt water with a different specific gravity depending on the salinity. Consider alcohol; it has no salt but does not freeze right? Beer's sg is slightly higher than water so it wont freeze til perhaps 30F.

Why is it easier to float is salt water than in fresh water?

Because salt water has a higher specific density than fresh water. (Specific gravity of water is like the density of an object.) Imagine floating in fresh water that has a lower specific gravity, like frothy white water in a river. It is very hard to stay above the surface in that water. So you float higher in water that has a higher specific gravity. Another way to put this is that the lower the relative density (your density divided by the specific gravity of water) the easier it will be for you to float. If the Relative Density is greater than one, the object will sink. If it is less than one, the object (you, for example) will float. so much salt lifts you up. try the paper clip and paper towel trick sometime In other words Salt water is heavier than fresh so therefore salt water can make you float.

How do you raise specific gravity in a salt water aquarium?

If there is no material that will corrode/react with the salt in the manufacture of the tank or its periferals then all you need to do is obtain the correct substrate, salt, heater thermostat, power filter, protein skimmer, ozonizer, living rock and learn about how to use all that stuff correctly then you can get whatever marine life you wish to keep.

Why does an egg sink in fresh water but float in salt water but stays in the middle when pour water into salt water?

Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

What has the highest specific gravity Styrofoam Water halite gold?

Gold has the highest specific gravity out of the options given, as it is a dense metal. Styrofoam has a low specific gravity because it is lightweight and mostly made up of air. Water has a specific gravity of 1, while halite (rock salt) is more dense than water but less dense than gold.

Does specific gravity of water is equal to normal water?

It isn't clear what the distinction is you want to make between "water" and "normal water". Water's density, or specific gravity, can vary slightly, depending on its salt content, other impurities, temperature, and even if it is pure water, its isotopic composition.

How long does salt last in salt water fish tanks?

Forever. The problem is, the water evaporates...and it doesn't take the salt with it. You need a hydrometer to test the specific gravity of your water so you know when to add more freshwater. (That sounds strange, but it's true: freshwater dilutes the saltwater so your fish don't die.)

Why do you float easy in salt water?

Salt water has salt and minerals in the water making it denser. When the water is denser it holds you up. The Dead Sea is so full of minerals and salt that you can just lay there and read. You don't even have to try. Salt water has salt and minerals in the water making it denser. When the water is denser it holds you up.

Do you ad salt to a salt water pool?

No. salt water is salt water. it already has salt in it

Does the great barrier reef have fresh water or salt water?

Salt water

Why do things float in salt water but not salt water?

Salt water is denser than fresh (not salt) water.
