Question

question 29 (1 point) in this virtual lab experiment, how is surface tension of water shown in the tensiometer activity? a it requires more force to lift the ring through waters surface than nonpolar liquids b nonpolar liquids always have stronger surface tension than water c surface tension is unrelated to polarity d it requires no force to break waters surface

Explanation:

Water is a polar liquid with strong intermolecular forces (hydrogen - bonding). Surface tension is the result of cohesive forces between liquid molecules at the surface. Polar water has stronger surface tension than non - polar liquids, so it requires more force to lift a ring through water's surface compared to non - polar liquids. Non - polar liquids generally have weaker surface tension than water. Surface tension is related to polarity as polar molecules can have stronger cohesive forces. And it definitely requires force to break water's surface.

Answer:

A. It requires more force to lift the ring through water's surface than nonpolar liquids
