Question

Salinity affects density. Choose all of the correct answers.

As water temperature decreases, water density increases.


As water temperature increases, water density increases.


As concentration of salt increases, water density also increases.


As concentration of salt decreases, water density also increases.

Answer 1

Answer:

2nd and 4th options are correct

Explanation:

2.)As water temperature increases, volume of water increases, hence density of water decreases.

4.) As concentration of salt increases, water density also increases as the salt when dissolved increases the mass of mixture and hence density.

Answer 2

Answer:

Salinity affects density. As concentration of salt increases, water density also increases.

Explanation:

What is Salinity ?

Salinity refers to the amount of salt that has been dissolved in a water sample. The salinity of the water increases as more salt is dissolved in it. The water sample with higher salinity will have more mass and hence be denser when compared to two water samples of equal volume.

Water density increases with salinity. This is due to the water's increased salt content. A high temperature reduces the density of water. Water loses density when it warms because its molecules stretch out.

The ocean density is directly proportional to the ocean salinity and inversely proportional to the ocean temperature. The density of seawater plays a vital role in causing ocean currents and circulating heat because of the fact that dense water sinks below less dense
