the fresh-water pond because it has a lower density

the fresh-water pond because it has a lower density

the salt-water pond because it has a higher density

the salt-water pond because it has a higher density

the fresh-water pond because it has a lower pH

the fresh-water pond because it has a lower pH

the salt-water pond because it has a higher pH

the salt-water pond because it has a higher pH

Answer 1

The correct response is:

the fresh-water pond because it has a lower density.

Freshwater typically has a higher surface tension than saltwater due to the presence of dissolved salts in the latter, which disrupt the hydrogen bonding between water molecules.
