salt water is denser than fresh water so it will produce more upthrust due to Archimedes principle

Why does a perspex block sink in fresh water but floats in salty water?
salty water is more dense than fresh
Why should an object sink in salty water and float in fresh water?
The only possible reason for that would be that after the object floated for a while,the salt ate a hole in it, the water poured into it, and it stopped floating.If the object doesn't corrode, dissolve, or get water-logged, then it might float insalty water and sink in fresh water, because salty water is always more densethan either fresh or distilled water.
Does eggs float better on salt water or fresh water?
viscosity of saline water is higher than that of pure water
Do objects float more easily in salt water or fresh water?
Adding Salt to the water increases the density of the water, and therefore makes it weight more per capita. This in turn causes the salty water to push down with more force then water with no salt, causes things that may not float, to float, and things that already float in normal water, to float higher in salty water.
What type of water would a swimmer float more easily?
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!

In which container did the egg float saly water or fresh water?
salty
Why does an egg float in water and not it salty water?
A fresh egg don't float in pure water; in a salty water the floating depends on the concentration of the salt in solution. The salty water is more dense.
Is salty water more sense than cold water or more dense than less salty water?
Salt water is denser than fresh water. A ship will float higher on the oceans, and float lower on a fresh water inland lake.
Is salty water more dense that salty water?
Salt water is more dense than fresh water. A ship would float higher at sea, and lower on a fresh water inland lake.
Do pieces of ice float in salt water?
I think that salty ice cube do float in water because ice bergs float it water and they're made of salty water. i think i depends on the density (Amount of salt) in the ice
Why is it easier to float in salty water tahn in flesh water?
It's easier to float in salty water because the water is not dense compared to fresh water. No its not! The other way around! The salt water is MORE dense than that of fresh water, so you float easier: there are more particles in that given space. :)
Is it easier to float or sink in salty water?
float

Is the river salty or fresh?
fresh :)
Is river salty or fresh?
fresh :)
Why do eggs float on salty water but not on ordinary water?
Salt water is more dense than fresh(tap) water. This allows the egg to float. It is also easier to stay afloat in the ocean than in a fresh water lake. Same concept. how much water do i use?
