The salt makes the water more dense ,so that objects can float on the water.
Salt actually increases buoyancy.
Because the density of salt water is higher.
=pressure = Force/ Area=
density
Because fresh water has a slightly lower density, which means that more water has to be displaced to create the same amount of buoyancy.
Adding salt in water changes the buoyancy of plain water because the salt makes the water denser. This shows when an egg is place in water with salt, it floats, while with plain water, the egg sinks.
more salt means more density so more buoyancy.
the salt water has more density than fresh, so it can carry more weight than fresh water.
An egg floating in salt water. The salt makes the water more dense. Since the egg is less dense it floats!
Salt water is denser than fresh water. Since the buoyant force is equal to the weight of the displaced liquid or gas, an object of a certain volume will have more buoyant force pushing it up in salt water than in fresh water. It's sort of the same reason we can float on water but not in the air. Air is so much less dense than water that to float in it we need to displace a volume of it equal to the volume of a hot air balloon.
No. Toys float better on salt water than on fresh water because salt water has higher density, and the ratio of density controls buoyancy.
Liquids that have a greater density than water, will provide more buoyancy to objects floating in it. Salt water is more dense than fresh water, so objects will float higher in it.
