how can alot ...and I mean ALOT...of salt make you float ? like the dead sea?

Question

whats in the salt that makes you float?

Answer 1

Just like oil floats over water. Even if you have 1000kg of oil and 1kg of water, the oil will still float over the water because of its density.
Adding salt to water makes its weight higher (in about the same volume) so its density gets bigger. The body contains a lot of water and fat. The density of the body is lower than the density of the dead sea, so we float.
It doesn't matter if water is liquid and our body is solid (like a cork or a bar of soap that floats in the bath).

Answer 2

has nuthin 2 do w/ salt, all the salt does is make the water mor dense. w/o the anything, water has a 1.0 density. nethin below tht floats on water. so u add salt to water it ups the density. if u add enough thn people and other things are able to float on the water, like in the dead sea

Answer 3

Because it raises the specific gravity of the water to that which is greater than the person floating in it. It's just like taking a piece of wood and tossing it in a pond. It will float (unless it's water logged). A piece of steel say, won't float.

The wood can displace enough water to keep itself afloat, the steel cannot.

When a person is in salt-saturated water they too can displace enough water to stay afloat.

Imagine it like millions of little tennis balls dispersed throughout the water helping to hold you up......that's the salt. WIthout it you would tend to sink.

Does this help at all?

Answer 4

Nothing in the salt makes you float. Salt itself increases the density of water, yes...but bouyancy is the force that "makes you float." Take your body weight, divide by the volume your body takes up. That is your density. Take salt water, and weigh it and divide by the volume. That is the water's density. If the water's density is greater than yours, then you will "float", or in more scientific terms, you will be bouyant.

Answer 5

lots the comparable as mentioned beforehand, salt is denser than water and, in addition to...that's correct on the grounds that this makes it greater dense than your physique that's around ninety% water (salt is clearly greater dense than water: think of your self sitting on a pool of salt and it will become VERY glaring you're able to drift and, in certainty, come on the element of being waiting to circulate slowly on it). So, in lots the comparable way much less-dense-than-water oil floats on the exterior of water you drift on salt water (notice that, say, if the density is say 2 (salt water) over a million (you) then a million/(2+a million) = a pair of million/third of your physique would be below water and that this formulation would not artwork in case you're heavier than the liquid you're in as though that's, say 2 (oil) over 3 (you) then it potential you're sinking at a fee of approximately 3/(2+3) = 3/5 physique quantity consistently).

Answer 6

its makes the water density higher than the density of humans, thus you float because you are less dense.
