Comprehension Passage
Evaporation showcases the dynamic interaction between liquid particles and their environment, key in numerous natural and industrial settings. This process is driven by surface particles possessing enough energy to break intermolecular forces, not because they are lighter or differently affected by air. The rate of evaporation is inversely related to humidity, as higher humidity means more water vapor in the air, hindering further evaporation. In terms of liquids' interaction with surfaces, mercury stands out as it does not wet glass due to its high surface tension, unlike water, alcohol, and phenol. This differential behaviour underscores the complex interplay of physical forces in evaporation and liquid adhesion.

Which of the following does not wet the walls of the glass vessel in which it is kept ?

1
Water
2
Alcohol
3
Mercury
4
Phenol
