Question

How does boiling affect density and salinity? Why does this happen?

Answer 1

I am assuming you are asking how boiling affects the density and salinity of salt water.

If my assumption is correct, then my answer is below:

Boiling salt water will  increase both salinity and density.  As water boils, water begins to leave as water vapor. None of the salt will leave.  Therefore, the salinity of the water increases. Increased salinity causes increased density.
