Question

The density of sea water. Explain how temperature affects it.

Answer 1

density of water maximum at 4 degree and when apply temprature density decrease bcz of space between molecule decrease

Answer 2

Answer:

The density of seawater at the surface of sea is around $\frac{1027 k g}{m^{3}}$. With a decrease in temperature the density increases.

Explanation:

The density of seawater on surface is $\frac{1027 k g}{m^{3}}$. It depends on two factors: the temperature of the water and the salinity of water. With temperature, it has an inverse relationship in which with a decrease in temperature, a density increases.

When sun rays fall on sea surface then the surface water gets heated up but, sun rays are not able to penetrate deeper into sea surface and as one goes to deep sea the temperature decreases. Keeping in mind, that density is inversely proportional to temperature the density keeps on increasing as one moves to the depth of the sea.

It also depends on salinity, the density increases with increase in salinity. That’s why in the water of Dead Sea one can float because it has the highest salinity and that’s why it also has the density so, that the people can easily float on it.
