Multiple Choice 5. Which property of water explains why seawater contains over 20 different elements? (4 points)


universal solvent surface tension high heat capacity high boiling point

Verified Answer :

B. Organisms
that live near the surface of the ocean because the freshwater is less dense
then the salt water and will rise to the surface. saltwater is denser than freshwater due to
the weight of the salt it contains. Because of this organisms at the
surface will face different environment that might affect them.

 

seawater
contains over 20 different elements because water is the universal solvent
