Question

you are comparing the surface tension on two bodies of water: a fresh - water pond and a salt - water lagoon. which one, if measured, would have a higher surface tension?
(1 point)
o the fresh water pond because it has a lower density
o the salt water pond because it has a higher density
o the fresh water pond because it has a lower ph
o the salt - water pond because it has a higher ph

Explanation:

Step1: Understand surface tension

Surface tension is related to intermolecular forces.

Step2: Consider salt - water

Salt (ions) in salt - water increase intermolecular forces. Higher density (due to dissolved salts) implies more particles. More particles lead to stronger intermolecular forces. Stronger intermolecular forces result in higher surface tension. Fresh - water has fewer dissolved particles (lower density in this context). pH is not directly related to surface tension in this comparison. So, salt - water (higher density due to salts) has higher surface tension.

Answer:

B. the salt - water pond because it has a higher density
