collect sea water in distilling flask. boil water. steam escapes, salt remains behind. use physical means to separate physical mixtures.
To be a true solution seawater must be filtered.
Swordfish are NOT amphibians, they must remain in seawater.
Seawater is first filtrated and then refined by repeated processes of crystallization/dissolving/recrystallization.
no.they must have fresh water to live.

On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram, or every litre, of seawater has approximately 35 grams (1.2 oz) of dissolved salts.Accidentally consuming small quantities of clean seawater is not harmful, especially if the seawater is consumed along with a larger quantity of fresh water. However, drinking seawater to maintain hydration is counterproductive; more water must be excreted to eliminate the salt (via urine) than the amount of water that is gained from drinking the seawater itself. The effect of seawater intake has also been studied in laboratory settings in rats.This study confirmed the negative effects of drinking seawater when dehydrated.
Seawater is first filtrated and then refined by repeated processes of crystallization/dissolving/recrystallization.
Seawater has very high levels of sodium , salt, from materials in the sand, freshwater, lakes and ponds, have very low, if any salt levels , so, never consume seawater without first filtering it, it will kill you.
Seawater is water with salt in it
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
