Question

The buoyancy of the sea water increases because of its
​

Answer 1

Answer:

The mass of the saltwater is much higher and the volume only slightly greater, so the saltwater is more dense than freshwater. If the same volume of water is displaced by an object, the weight of saltwater displaced is greater and thus the force of buoyancy is proportionally greater.

Answer 2

Answer:

The buoyancy of the seawater increases because of its salinity.

Explanation:

Salt increases water's density by increasing the mass of the water.

• When salt is dissolved in water, the dissolved salt contributes to the mass of the water by making it denser than freshwater.

• As a result, saltwater weighs more than freshwater, so it exerts a greater force on a submerged object

• The upward buoyant force increases as the density of the fluid increases, making the object float better in saltwater.
