It's always (relative) density.
If you just barely float in salt water, you will sink in fresh water.
Any number of things will float in fresh water. Any boat that can be used in salt water will also stay afloat in fresh. However, fresh water has a lower specific gravity than salt water, and as a result, objects that displace a certain amount of sea water will displace more fresh water; they will sit lower in fresh water.
i think it is ppeople because they float in salt water and sink in fresh water.
Yes, it is easier to float in salt water than in fresh water due to salt water's higher density. The salt content in the water increases its buoyancy, making it easier for objects and people to float on the surface.
It is definitely easier yo float in salt water.
Assuming equal temperatures it does not. The fresh water will be on top.
on fresh salt water
Yes, salt water is denser than fresh water so boats float higher in salt water.
Because salt is dense, so denser the water the better you float!
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft Everthing else that is above 62.4 lb/cu.ft will sink, anything below will float.
Objects float higher in salt water compared to fresh water because salt water is denser than fresh water. The higher density of salt water provides more buoyant force, causing objects to float higher. Additionally, salt water can also affect the rate at which objects sink or float due to changes in the water's viscosity and surface tension.
Objects float more in salt water compared to fresh water because salt water is denser. The increased density of salt water provides greater buoyancy for objects, allowing them to float more easily than in fresh water.
