Every 10 metres, the pressure increases by one atmosphere, so, at 10 metres, total two atmospheres, it would double, to 50 litres per minute. Ten more metres, total three atmospheres, three times surface, or, 75 litres per minute Fresh and salt have the same pressure, the only two real differences are buoyancy; salt is more buoyant, and then...there's taste psi is an old measure of pressure, not volume
Sodium would be 0.99%
It depends you the divers lung capacity and how many breathsper minute they take. But in general it would be 1.3 to 1.8.
If the world did not have any divers, it would be havoc! There would be no knowledge of the moss on the rocks on the bottom of the ocean. Oh no! 'o'
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater
It is better to use the muddy puddle water than the seawater because of the salt
Urine does not dissolve, no. It's there in the seawater along with all the fish urine and seal urine and dolphin urine and pelican urine...
Yes because the intake of salt would be harmful to it.
How would anyone know your car gas consumption? Only you can answer that.
