Question
Which of the following water types would be the densest?Group of answer choicesa. Warm, salty waterb. Cold, freshwaterc. Warm, freshwaterd. Cold, salty water
Solution
The densest water type would be "d. Cold, salty water".
Here's why:
-
Temperature: Cold water is denser than warm water. This is because when water cools, the molecules move slower and get closer together, which increases the density.
-
Salinity: Salty water is denser than freshwater. This is because the dissolved salts add mass to the water without significantly increasing its volume, which increases the density.
Therefore, combining these two factors, cold, salty water would be the densest among the options given.
