CHM 101 Chemical Bonding and Intermolecular Forces Objective Question

Question

What is surface tension?
Options
A The pressure inside a liquid
B The result of the net inward force experienced by molecules on the surface of a liquid
Correct Answer
C The boiling point of a liquid
D The ability of a liquid to evaporate
Correct Answer

Option B is the correct answer.

Detailed Explanation

Surface tension results from the net inward force experienced by the molecules on the surface of a liquid. Molecules at the surface have fewer neighboring molecules to attract them, creating a tighter, more cohesive surface layer.

Hint

Surface tension causes liquids to form droplets and allows insects to walk on water.
